Im looking to buy a small hang on uv sterilizer. I just got a free 25w one my boss gave me but has no pump. My question is do the small twist sterilizers or any small sterilizers have an internal pump? Or do all uv's require a seperate pump for it to function? I really wanted to a get an all in one but now im not sure if they make em.

The CoraLife Turbo Twister needs a separate pump. There is a Chinese company that produces a brand called AA - - they produce a small, self contained UV Sterilizer. However, I have tried to find the flow rating of the power-head (essential information if one is going to determine the correct size of UV unit) and they have not provided it. You will get pretty good information off of the Emperor Aquatics web site. Also, look for material (try the library) written by P. R. Escobal - - - his info is technical, but once you understand the fundamentals, you will be able to choose a Sterilizer that will work, rather than wasting money on something that is inappropriate . . . a false sense of security will bite you in the ass sooner or later

seems you like P. R. Escobal's work. but i would say... UV technology has greatly improved in the past 7 years. the 1st ed of escobal was in 1996 and the second one was 2000. Seven years ago is quite long i would say... the books cost more than $200. hopefully it is easily seen in libraries. with 206 pages... wow! i would go for the flow rate on the manufacturers manual. they cannot falsify those as they are liable to law suits if it was incorrect.

You didn't give us enough info...
1) Size of tank?
2) Fish being kept?
3) Planted tank?
4) filter system?
That 25w UV is overkill for a small tank but wouldn't harm anything (especially if the bulb is old
) you can attach a small pump to it if you have the room ( http://www.harborfreight.com/cpi/ctaf/displayitem.taf?Itemnumber=47117 ).Petsmart has a couple of selfcontained units http://www.petsmart.com/global/prod...64&itemNo=9&Ntt=Uv&In=All&previousText=Uv&N=2

There was just something so nieve about that statement..we are talking about imports from China here

nothing in the world of physics has changed since 2000 in the way of UV.
all his info is still up to date....the book lists for $30 but is out of print
aquatic systems engineering... p r escobal
When I quit using my Turbo twist UV after the bulb died, I never noticed one iota of difference to my tank. For most setups, good filtration and water change regimen is all you need. UV is usually unnecessary expense IMHO.
"UV is usually unnecessary expense IMHO"
the key word is usually !! if you dont have an adequate quarantine tank i believe the UV done correctly buys some insurance

exactly... I'm talking about regular average tank setups, using established good fishkeeping techniques. Its always good insurance if you want to buy it, but for most people you aren't going to gain enough that the money wouldn't be better spent elsewhere.That's just my 2 cents, I know some people swear by them.johnptc;896275;896275 said:

Calculus has not changed in 7 years, and that's the basic foundation of his work. The CoraLife TurboTwist and the Pentair AquaStep have the advantage over the older technology in that they do improve dwell time, but they compromise other issues as well. Some manufacturers indicate a maximum flow rate, but they don't tell you if that rating is to zap algae, bacteria, fungi or protozoans. If memory serves me correctly, Emperor Aquatics & CoraLife do have charts or graphs on their web sites that show the zap dosage @ various flow rates. However, even with knowing the Zap dose, we still need to use calculus to determine what flow is required to have all the water pass over the UV tube twice per day (at that rate, it is considered that the pathogens are being killed off faster than they can reproduce) - - keep in mind that every drop of water that passes over the UV Light falls back into a tank of contaminated water, hence the need for the calculus.
Marketers have a way of wording things that can often be misleading, yet not create a situation that leaves them open to lawsuits.
Thanks for the challenge to my post . . . this is the only way we can get to the root of anything & I appreciate the reminder of the advances in technology as it helps to keep the "Big Picture" in view.
