This one is pretty darn good!

I've been using UV lights on multiple set ups for over 7 years... I've tried several and have reviewed many...
Turbo Twist is a favorite as they work well, are readily available (as are replacement bulbs), the hang on tank clip makes for easy installation...
Danner Pondmaster UVs are my absolute favorite. They are fully submersible and are built like a tank. I'm pretty sure you could beat an intruder with it and not break anything (except the intruder).
For maximum benefit (including killing parasites) I highly suggest:
1W of UV per 10 gallons of volume in your system...
10 gph per 1W of UV strength...
Thus an 18W or 20W would serve you well...

When I tried looking for a Danner Pondmaster UV, the smallest unit I found was a 10 watt good for a 1000 gallon pond. What size tank are you running your pondmaster on?
Danner Ponmaster UV lights come in 10W, 20W & 40W...
The "up to 1,000 gal ponds" rating of the 10W unit is for getting rid of green water only.
The more complex an organism is, the more resistant it will be to the UV's effect. Thus to kill parasites much more UV exposure is necessary. If you dig deep enough in the manufacturers information I'm sure you will find their version of such information. But we must always be careful as manufacturers will often exaggerate the effectiveness of their product.
I've used UV lights for several years in conjunction with raising and breeding Blue Dempseys which are well known to be prone to parasitic infections. In the coarse of doing so I've become very confident in the previously noted ratio for UV sterilization.

Why are some UV Sterilizers expensive and others are not? They are they same watt but one is $44.90 http://cgi.ebay.com/UV-18W-Ultravio...tem&pt=LH_DefaultDomain_0&hash=item439f3e62a6 and others are $133.99? http://cgi.ebay.com/Coralife-Turbo-...tem&pt=LH_DefaultDomain_0&hash=item439f1b2b05 Will the $44 one work on my 180 gallon tank? To kill parasites, get rid of algae and clarify algae?
Why are some UV Sterilizers expensive and others are not?
Brand Name and materials used.
Will the cheaper one work just as well as the more expensive, maybe.
Will the cheaper last as long as the more expensive, again, maybe.
Mini Rant Ahead
Ever since we allowed the bulk of our manufactured goods to come out of China, buying equipment has become a real crap shoot.
Trusting a brand name and paying the premium for it does not equal quality and long service life..
The same factory that produces the brand name unit during the day shift, could very well be pumping out clones during the second and third shifts.
These copies, most often, will be made with cheaper materials and a different name.
Are they the same, well, pretty close.
Considering you can get 3 of the cheapos for the same money as 1 name brand, with no guarantee of superior craftsmanship and they all come from China, I know what my choice would be.
Oh yea, don`t forget to order your China pump to run your China UV.

well... to comment on above, i did go through 3 china UV before i settle on my turbo twist ^^;; is turbo twist made in china too, i dont know, but at least i paid more for all 3 of the china's combined .... turbo twist works so much better too... i have a 36w on my 300... and a 36w on my 180, which is overkill i believe, but, water is clear, fish is healthy, its all good.
Pond/Aquarium UV clarifiers/sterilizers emit UV-C rays. This is acheived by adding a chemical/gas to the bulb. So a "cheap version" would most likely add less gas which would make the same wattage UV lamp emit weaker UV-C rays...
The UV housing will have water flowing through it and thus must remain 100% water tight. Cheap construction or cheap seals may allow the housing to leak.
The electrical components are pretty simple, so there shouldn't be much of a difference. but I'm sure they'll save a penny there too if they can.
Does that mean we should always buy the "name brand" or the more expensive model, no... but does that mean we should always buy the cheaper version, no...
The less expensive version will always be utilizing methods to save a buck... but in this day and age chances are the "name brand" is too...
(frikkin China! Makes ya wanna kick the SOB that sold our manufacturing to them doesn't it...)
