If it ran too little of water it killed many good things that help a tank, but if you are looking to kill just 'parasites", bacteria, ich etc etc you need to run alot of water through it.

I have a 40 watt Aquaviolet and was told to run 900GPH to kill just the "bad Stuff, and only 600 gph, will kill everything, including the good things. I believe the numbers I quoted are correct, but has been awhile since I set it all up, but talk to your manufacturer to get right info. http://www.aquaultraviolet.com/sites...20UV%20FAQ.pdf

The belief is that you just run water thru it and all is good. This is not the case, as per Aquaviolets, tech guy, whose info was provided to me verbally.

I have 55w Uv sterilizer on my tank and I have no problem.I have 4 blue tangs and they are all happy and never had any issues with ich,so I think the uv light is a very good prevention.
