Definition of Ad Hominem. What is also noteworthy throughout this article is I DO provide references, and yes a lot of information is based on my own vast experience and experiments where by I then arrived at product I would recommend.

So in the end if you were to "follow the money", my financial incentive was NOT to sell UVs, rather to to put together a system that worked and which included far more than UV sterilizers, such as quarantine, feeding, water parameters, etc.

For the critics of what products are promoted, of course I promote products, as I run a business. HOWEVER, I have professional experience dating back to longer in the hobby , and I have used and experimented with most well known brands with literally over applications. In other words, for me to sell anything other than what I know to be the best would be dishonest!! Purchasing elsewhere such as Amazon will only result in this free information going away someday!!

For the most updated, researched aquarium light information: Researched steps for a healthy aquarium: If turbidity is high and bio filtration is low, you could require double rated UV. In ponds in particular, it often takes double the normal rated size UV Sterilizer if bio filtration is poor and turbidity if high just to clear green water.

In fact this is where most UV Sterilizers installed in ponds fall short as pond keepers will place as an example a 9 watt UV powered with a gph pump which is times the effective flow rate for a pond installation often as per very poor directions by the manufacturer.

This problem is also common among reef aquarists with high flow rate sump pumps attached to UV Sterilizers incompatible with the flow rate, resulting in the common and incorrect statement that "the UV Sterilizer was useless". I will state based on many years experience and experimentation that will the calculations provided here are THE MOST accurate, not exaggerated claims by many UV manufacturers. This is a very simple explanation, and there is more to this including sterilizer design, etc.

More in the section about UVC Penetration. These shields will not only help move water the entire length of the Sterilizer body, but also keep the water flow less linear and thus keep any particulates we wish to sterilize in the unit longer more about design later in the article.

Please read this section for more on this important subject: Simply put, in clarification, algae cells are not killed as the UVC strength and dwell time is not enough to kill , rather they are clumped by the UV energy, which causes the algae "clumps" to either fall out of the water column into the substrate or get picked by the filter s.

It is noteworthy that if you pond or aquarium does not have a healthy bio filter, this aspect should be explored first. For a positive check of flow rate, simply use a stop watch many cell phones have this feature , and place a container under the outlet. For example if one gallon is filled within 10 seconds, this is 6 gallons per minute or gph.

Many people are surprised how slow their pump actually is after applying head pressure. Some pumps or filters lose head pressure more quickly than others such as the Hagen Fluval , while other pumps are specifically designed to maintain higher head pressure over greater vertical distances such as the Rio HF Series Water Pumps.

See also this article about head pressure: Another consideration is the size of the PVC pipe or tubing coming from the pump. It is also noteworthy that the flow rates I have already noted is not an exact rule, as reflection within the UV Sterilization chamber, the distance between bulb or sleeve and the walls of the unit, and the length of the bulb as per wattage of UVC output all affect this general guide this is explained later in more depth.

The point as to bulb length is noteworthy, as I have found that increasing wattage with the same length bulb does NOT increase effectiveness proportionally to a given wattage. This method will allow the proper flow through your UV Sterilizer while maintaining flow rate with the remaining filter system with no added back pressure.

This is better than adding just a ball valve which will add back pressure and then also slow flow rates making the filter system less efficient. The reason is these flow through diverters cause turbulence where the water enters the UV and the result is a poor flow rate through the UV even if the valve bypassing the UV is partly closed. This principle applies to aquarium systems too! It is important to have a flow rate that will turn over the pond or aquarium at least once every 2 to 3 hours for green algae control, once every 1 to 1.

While higher turn over rates compared to slower flow rates in the UV might seem counterintuitive, it is not when one looks at the reason why. The reason for higher turn rates for higher levels of UV Sterilization is to provide a better chance for all pathogens to get proper UVC exposure and to not recover before passing back through the UV Sterilizer once again.

So by having a higher turnover, along with longer dwell time, this more readily prevents the recovery of these pathogens. When applied, this means the same UV Sterilizer that might work for level one sterilization will not work for level two sterilization and a larger size is needed.

As one example, a Vecton 8 watt with a flow rate of gallons per hour might work great for 30 gallon aquarium for level two sterilization with a turnover of approximately 3 times; however a 60 gallon aquarium will only have an approximate turnover of approximately 1. This is explained with more examples in the What size UV is best" section of this article. As a side note, from my experiments and use of many different UV Sterilizers and configurations over the years, flow rate is still more important than turn over, so as long as you are reasonably close, I would not get overly stressed on this parameter there are other considerations too, so please read on.

A turnover rate can also be less than accurate based on your method of plumbing; for instance if your water inlet and return are situated immediately adjacent to each other you will have areas of the aquarium or pond that are not well circulated. Based on "house calls" I have made, adding additional power heads or other circulation devices do NOT make up for a poor flow pattern!!

The picture to the left shows the point I am making. With sump use , many will simply place a UV Sterilizer in a loop circulating within the sump. This too results in re-circulation of UVC irradiated water while most of the aquarium does not benefit from the use of the UV Sterilizer. This is also why a submersible UV Sterilizer will never work correctly when placed in a sump, especially for level 1 or higher UV Sterilization. With a sump the water needs to be returned directly to the aquarium after passing through the UV Sterilizer for maximum efficiency not connected with pick up and return from the sump.

HOWEVER, I will point out one exception; A long sump such as 24 plus inches or really any shape that allows the outlet pump to be isolated on the opposite side of the sump via a "gate" or similar from the inlet of water from the aquarium may work. The test is simple, by placing a dye into the inlet and watching to see if the water goes directly from the inlet to the pump, without any circular motion within the sump.

If this checks out, then connect the UV Sterilizer with a separate pump placed near the inlet and the outlet from the UV near the pump that is returning water to the aquarium Please click on the picture to enlarge Often this seeming contradiction of low flow rate versus higher turn over rate confuses some persons, but it is logical when one thinks about it, hopefully the table below or the more in depth sections further in this article will shed more light on this important aspect of correct UV Sterilization.

Another way to look at this is if you have a 75 gallon aquarium with a 25 gallon sump and you desire level 2 sterilization, you have a combined gallons of water, so three time turnover per hour equals gph. Then if using a high dwell time UV such as the the TMC Vecton or Aqua Ultraviolet, a 25 watt model x 12 gph per watt also equals gph; so gph is your magic number in this example. Keep in mind that two 25 watt UVs can be placed on line or on separate loops at opposite ends of the aquarium for larger aquariums.

Also note that this example is for level 2 Sterilization, and that most situations call for only level 1 Sterilization for which a high dwell time UV as small as 8 watts would be all that is needed. Also many connect their Aquarium UVs to high flow sump pump that provides a flow rate well above level one sterilization. Make sure to either use a ball valve if the pump only needs minor adjustments in flow, a diverter valve, or simply use a second lower flow rate pump to attach your UV Sterilizer in-line from your sump back to your aquarium.

As well many will correctly install a UV Sterilizer for their pond, ignoring the importance of good filtration combined with UV Sterilization.

A correctly installed UV Clarifier often will not over come poor filtration and circulation. This diagram can help determine flow rates at certain head pressures if you own such a pump please click to enlarge. A UV Sterilizer will easily work twice as hard or more requiring double the normal wattage or more if your bio filter is not adequate and water turbidity is high; this is especially a common problem with ponds. A water temperature between 20 C 68 F and 40 C F A gap of 3 cm or less between the bulb or quartz sleeve and the wall of the unit A reasonable dwell time, as most low cost, filter equipped UVs, and submersible UVs have poor dwell time Reference: As one can see, there is obviously some variance in the gph per watt, this is not meant to be vague, but to reflect the variance in UV Sterilizers themselves.

This is not a perfect formula since it does not factor in dwell time, temperature, and pre-filtration. In my three decades of experience using and even building I have found the formula I espouse here to be the most reliable, especially when one attempts to factor in the somewhat more subjective variables.

This is important to note as low pressure lamps are sensitive to water temperature while medium pressure are not the poor efficiency of medium pressure lamps which produce much of their light in spectrums useless for sterilization makes this only quality negligible.

The keyword is OPERATING temperature as in a reasonably well designed unit the water is usually in the unit long enough to be warmed several degrees which generally means that a water temperature over 20 C 68 F will work fine.

So if your flow or unit design or both is not allowing this temperature, your effectiveness will be minimal. The graph to the right shows general UVC "killing" power at a given temperature and given dwell time.

Quartz glass is also used in some UV Sterilization applications to protect a UVC light that is suspended above the water from spray assuming the quartz glass is kept clean of mineral buildup.

Which brings me to key 3, keeping the bulb or quartz sleeve clean? First, you want to change the UV bulb every 6 months for disease prevention or once every year at the beginning of the growing season for green algae prevention. You want to clean the quartz sleeve at this time too using acetone. With a simple model without a quartz sleeve, you just throw away the dirty bulb.

Premium UV Lamps product resource: High Efficiency UV bulbs. Another important factor that is often overlooked and sometimes controversial as per my reading of some forums, especially reef forums is the waters UV Transmittance. Water turbidity dissolved waste particulates, DOC, etc.

Even then, the best of this type of UV Sterilizer the SunSun is primarily intended for green or cloudy water control. The maximum intensity provided by a single UVC Bulb is at its surface.

So, if we calculate the surface area of the UVC lamp and only use that area which effectively emit UVC light rays, the effective area of UVC transmission will be established. Another aspect that might be important for us to visualize is the nm UVC light photon is more energetic than say or nm blue light, with a higher frequency.

Another point to understand that while photons travel in a straight line in a vacuum, in our UV Sterilizers filled with water these photons do not all travel in a straight line. As well, unlike red light which has a low frequency, low energy, long wavelength and can bend around things and go through things without harming them; UVC being a higher frequency has more vibration and a higher chance of interaction with any given particle.

The photons with the smallest wavelengths have the greatest mass and energy and the very largest photons have fleetingly small masses and energies. When I used a 30 Watt UVC bulb in a unit with over twice the exposure as the 15 Watt, the kill rate more than doubled. Experiments can also be safely conducted with standard household light bulbs to correlate penetration. Continue this with higher and higher wattage bulbs.

This is also assuming the design of the UV Sterilizer maintains a consistent. This is where some designs such as the "Twists" may fool the one into assuming a long exposure time, while in reality a good portion of the exposure time was past the most effective 3 cm range.

In the case of water which is what we are dealing with , this can vary considerably with dissolved solids, mineral content, organic content and more. This is why pre-filtering water is important for proper UV Sterilization. Water that is still laden with minerals, organics or more will need more UVC radiation in terms of Watts and time exposure.

Agitation of water being sterilized generally increases sterilization effectiveness. For more on this subject, please see this article: Effect of UV Sterilization on minerals, chemicals, etc. This is an area where a lot of information is posted in aquatic forums and similar that has little scientific proof to back up statements. I myself have noted the affect of UVC radiation on a variety of chemicals added to treat infections and I have noted a variety of end results, HOWEVER I also have not conducted hard scientific studies nor have I found any reputable studies to make conclusive statements although many persons do without much to back themselves up.

I however have observed UVC radiation breakdown some light sensitive antibiotics such as Quinine Hydrochloride. A few other proven UV sensitive antibiotics include: Obviously most organic compounds are either destroyed or weakened by UVC Sterilization at optimum levels. As I have noted elsewhere this includes nitrifying bacteria, HOWEVER this bacteria is rarely in the water column and should NOT be in the water column, so this is not a problem under most instances other than adding cycling aids during such time UVC Sterilization should be discontinued for 24 hours as noted earlier.

So for hormones the UV Sterilizer can be used as a tool that is turned on or off depending upon the needs of the aquarium keeper for controlling their aquatic environment. It is however noteworthy that iron, sulfites, nitrites, and phenols can absorb UV DeMers and Renner, This does not mean that UV Sterilizers are useful for removal of these compounds, rather that the presence of these compounds in water lower UV Penetration and thus effectiveness.

Here are a few examples for level one sterilization and basic clarification, then I will explain in more depth with even more examples accompanied by pictures. In this example I will look at the capabilities of a few UVs as per maximum size of pond or aquarium for the two most common UV applications; Clarification and Level 1 Sterilization.

Then multiple by a turnover of once every three hours which equals a gallon pond. As with the Advantage, the Tetra 18 watt can maintain a gallon pond.

Then divide this number by a turnover rate of 1. Please note that many other factors make this a generalization such as filtration, bio load, the presence of a Veggie Filter in a pond , and of coarse the UV itself Example 2: So as a minimum you would need a flow rate of 50 gph assuming once per 2 hours in water turnover.

At 50 gph for turnover the smallest UV available is a 5 Watt which can have a flow rate up to gph 5 x 50 gph for clarification. For Level One Sterilization generally the most common application in aquariums , you would need a turnover rate of 1.

The flow rate through the UV should be gph per watt I will use 20 such as required with a Jebo UV which would mean 7. The flow rate in gph per watt is generally gph sometimes even lower, we will assume a lower efficiency UV and use 8 gph per watt for this example , so at gph this would require a I say "strangely popular" because the Turbo Twist has a gap of more than 3 cm at many points during the water pass due to baffles, as well this UV has many known issues with its ballast, which makes me wonder why such a poor UV is so popular!!

Again I want to emphasize the previously given flow rates are generic generalizations that do not take into consideration UV design, water temperature, water turbidity and more. Water that is not pre-filtered is going to be more turbid higher TDS and require a lower flow rate, as well the design of some UV Sterilizers often necessitates a lower flow rate as well. With all these examples, you will note that the UV Sterilizer is always after the pump and the filter.

The pump obvious has to be first to initiate water flow. The Filter should be first for two reasons: For one the filter removes particulates that will impede effective UVC irradiation as noted earlier in this article. As well, having the Filter first allows for establishing of necessary nitrifying bacterial colonies in the filter. Here are a few more installation tips: The reason is if the chiller is being run by a thermostat probe in the aquarium, it is going to be cooling the water that goes through it much more than the water in the aquarium itself until the temperature comes down.

This is a problem since UV Sterilizers operate more efficiently at higher temperatures and the water inside the lines FROM the chiller are likely to be much cooler than the aquarium water when the device is running. Based on my experience in s of applications, even UVs designed for pond use can prematurely fail due to poor placement. See the Myths section for more about this subject. The best way to look at this is if you have a 15 watt UV Sterilizer, consider this a 15 watt ambient heater that is constantly running.

Is this likely to be a problem with a gallon aquarium or pond? NO, but maybe so a 10 gallon. Also, based on considerable aquarium design plumbing experience, I would be weary of most disconnects sold by pump, filter, or any other aquarium supply manufacturers as while simple, these are usually light duty and are much more prone to leaking than much more durable PVC compression union disconnects which use a more sure screw on method and much better O ring.

See the picture to the right. Multiple units in parallel or immediately inline with each other work well for larger ponds or aquariums. The in-line Vecton UV8 V2 pictured is a good example of this design that is offers the superior long exposure straight tube design in a more compact easily adaptable design that is superior to ANY compact in-line UV Sterilizer including the Terminator which I also still recommend.

The picture to the left shows a Vecton , 8 Watt UV mounted to a twin canister filter combination as well as a CO2 injection system one canister filter is run as a bio filter only in this example. Taking the very high dwell time Vecton UV a step further, the picture to the left picture demonstrates these products: This is a simple yet VERY effective way to connect a premium high dwell time UV for level one or higher UV Sterilization utilizing a simple power head and sponge pre-filter for maximum effectiveness.

The small valve included with the Rio and many other pumps as well such as the Via Aqua can be used to slow the flow during critical times when a higher level of UV Sterilization is desired. The UV is mounted on the side only to better display how this is done; back mounting is suggested for better aesthetics. The picture can be enlarged by clicking on it too! This kit can be found here: Probably the most common UV Sterilizer Application is to a Canister Filter or Pressurized Pond Filter these pressurized pond filters make an excellent alternative aquarium canister filter as well.

The picture to the left demonstrates a Vecton 8 Watt, very simply spliced "plumbed" in-line from the return side of the Vecton UV Product Resource: HOWEVER I recommend replacing the Fluval tubing with standard vinyl tubing as in the picture to the left since this is a poor quality tubing anyway that easily cracks.

For this, using a hose barb adapter as pictured to the left is often a very simple "fix". This is an excellent idea in theory that also has many flaws. The first generation internal UV Sterilizers which are still sold by places such as Amazon have leakage and reliability problems as well as flow design problems.

The second generation still has flow design problems. For help in connecting aquarium tubing to hose barbs or similar connection please click this picture. One exception as per flow rate is once you get below gph per watt, this can produce to much heat and shorten the life of your UV Sterilizer or Clarifier. Another exception is not necessarily "too large" rather is simply a waste of money.

However while parasite and some virus and other control results are better than 20 gph per watt, it is not double or more the result one would get over a 20 gph per watt application with this particular UV. While it may be true that parasites such as Cryptocaryon marine Ich , are more readily killed at this rate, this is not an established fact, in part since it is impossible to force all Cryptocaryon tomites in an aquarium through the UV Sterilizer.

As well in a marine reef tank in particular, this high wattage to flow ratio may kill copepods or other propagated organisms assuming they get into the water column, which is rare. While the facts that many of the organisms propagated in marine reef are not killed by typical UV flow rates 20 gph per watt , making it a MYTH that UV Sterilization should not be used in reef aquariums, I would also not push the envelope with flow rates much under 10 gph per watt.

Many if not most sold are not even capable of level one UV Sterilization. As an example, a Custom 15 watt UV I personally have built in the past is effective when installed properly in part because it is flow restricted and will not allow more than gph necessary for level 1 UV sterilization. UV sterilizers that place the UVC lamp above the water are generally less effective or insert the lamp inside the filter, again due to poor UV-C exposure. In this case, a pond skimmer itself is a terrible idea carried over from pool persons not aware of what it takes to filter a living pond.

Complete Pond Care Information. Other designs of UV Sterilizers which have suddenly re-surfaced, that have been around before as far back as the s are those that mount to Under gravel filters and "Hang on the Back Filters". Nektonics was one of the first manufacturers to experiment with these ideas I too used and tested these in the late 70s and early 80s.

The problem is not usually flow rate, rather a poor design that does not allow for correct turnover, exposure distance from the UVC lamp, and contact.

While these may seem like a good idea I thought so too initially until testing showed otherwise , in practical test these all failed level one sterilization tests, yet alone level 2 sterilization which is claimed sadly by "My Aquarium Box". The facts are these are at the very best UV Clarifier poor ones at that. As well as some new Aquarium Canister filters that come with built in UV Sterilizers in the top such as the Grech, SunSun, and related canister filters.

In fact you will likely pay twice as much for the Tetra over the Terminator only for a slightly thicker plastic housing, and despite some common perceptions, neither should be kept in direct contact with weather and both are only water resistant, not water proof.

I will also add for pond applications, generally a watt of any brand is too small but for the smallest of water features. As a side note, I as the author of this article which not only represents s of hours of research, but many years of practical use and controlled tests obviously hope to sell a quality UV Sterilizer that I choose to make available on my web site of which the mark up is extremely low so as to make them more readily available.

This does NOT discredit the research and experience that has gone into this article, nor does this mean that there are not many good UV Sterilizers available elsewhere such as Aqua, Emperor, etc. It is also noteworthy that there are also several UV Sterilizers that are of poor quality that are not worth purchasing at ANY price I will leave mentioning many of these to blogs and reviews. UV Sterilizer maintenance is quite straight forward; make sure you keep your unit dry on the outside, if used for a pond try and protect your unit from harsh weather.

Most quality sterilizers can withstand the outdoor environment, however if allowed to sit in water, this water can seep in and damage electrical components. This video might be helpful for a UV Bulb or quartz sleeve change. More importantly; CHANGE your bulb every 6 months for aquariums, and also every 6 months for ponds in warm climates where there is no winter freeze. It is also noteworthy based on my experience , that a so-called "long life" UV Replacement bulb is a marketing ploy.

The facts are that while these might "burn" longer, these are also a lower output UV-C lamp and thus defeat the purpose to use. Quartz Sleeve; If your UV has a quartz sleeve it is important to clean the quartz sleeve when changing your bulb or at least every other bulb change, this is especially important with pond UVs.

Otherwise your bulb change will not be very useful. This need for cleaning becomes a MUST with pond use , and in my experience wipers do not alleviate the need for cleaning.

Be very careful when cleaning a quartz sleeve as they are very fragile and expensive and usually hard to find replacements. I recommend cradling the quartz sleeve in an old pillow or towel while cleaning and using acetone to remove scum and other deposits not glass cleaner. Do not clean in a sink, as it is very easy to break there in! As noted before, some UV sterilizers come with wipers which are used keeping your quartz sleeve somewhat clean between bulb changes, however they are more of an expensive gimmick my experience with them is they do little to remove build ups that block UVC light and still do not take the place of cleaning your quartz sleeve at bulb change time.

If left running with this crack which may not be easy to notice , this will damage electrical components to the point where the UV is NOT reasonably repairable at a cost less than a new UV Sterilizer. Another important note is that many UV Sterilizer manufacturers do NOT make their Quartz Sleeves available to retailers at reasonable prices; the result is if your Quartz Sleeve is broken beyond repair sometimes small cracks can be repaired with a small bead of silicone on the outside of the Quartz Sleeve , it is simply cheaper to replace the entire UV Sterilizer.

TMC is well known as a company especially in Europe that not only builds premium products, but ALSO supports their products with replacement parts at reasonable prices!! This is more true of the electronic ballasts than magnetic, although the starters used with magnetic ballasts often need to be changed every year. As well many of the low quality units that are now flooding the market often have cheap electronic ballasts that last 6 months to a year. With magnetic ballasts, make sure to check the starter first, as magnetic ballasts can often last for 25 years while the starters often last six months to 2 years a fluorescent starters function is to send a delayed shot of high-voltage electricity to the gas within the fluorescent bulb.

Keeping these on hand might be a good idea, however with proper care including lubrication with Petroleum Jelly, I have had these parts last many years. Pre-Filtration; Since pre-filtration is very important, make sure your filter pre-filter is kept clean where water runs well with as little water turbidity as possible.

When using Pre-filters such as the Filter Max or Hydro Pond as well as the Sponges that come in submersible UVs such as the SunSun CUP series; these should be checked regularly, usually once per week to two weeks in aquariums and as often as every few days in ponds use of rock pre-filters as well is suggested for pond use. The video below demonstrates the repair of a UV Sterilizer body: A UV can aid in cure by killing bacterial pathogens in the water column and fungal spores.

As well cure can be helped by improvement of water quality and of the Redox potential which is much more important than many realize based on scientific research. This is a fact as per controlled tests I performed in the s!

Even when run at a low flow rate gph per watt depending upon UV Sterilizer for level 2 , a UV Sterilizer cannot kill all Ich or Crytocaryon Tomites or Oodinium Dinoflagellates in the water column, as it is impossible to force all these Tomites to pass through the UV. However increasing the aquarium turnover rate through the UV Sterilizer times per hour or more , increases the number of these Ick Tomites or Dinoflagellates killed.

As well pre-filtration, especially with a micron filter placed before the UV Sterilizer can further improve effectiveness of the UV. A micron filter of 10 microns is very effective by itself, but can lower flow since it is very fine, so often a 50 micron pre-filter will suffice when combined with a high dwell time UV run at level 2 Sterilization References: One is they will solve all your problems, and Two they are useless.

A UV sterilizer will not kill beneficial bacteria- TRUE; when used correctly, bacteria such nitrifying aerobic bacteria are effective when attached to a surface of high water flow such as the sponge of a sponge filter, not when in the water column. In fact relatively new scientific evidence shows nitrifying bacteria to be sticky and adheres to the surfaces like glue this is why the myth of UV Sterilizers killing beneficial bacteria is just that, a myth.

It still may be best to turn off a Sterilizer unit when introducing bacteria in liquid form to seed a new aquarium. Better results yet are achieved if the filter running ahead of the UV is a micron filter. Just masturbate to their pictures I like jeeps and tacos. I wish my dog could talk!
