UV Sterilization Recommendations?

[YourPalCM]

Can anyone recommend a good UV Sterilizer that would work well with a Fluval 404 filter?

TetraTec makes a simple 5 watt UV. It goes for about $90 online.

Other companies such as CustomSealife make more complicated (and probably better) UVs with higher wattage...

e.g.: http://www.aquabid.com/cgi-bin/auction/auction.cgi?waterq&1090427104

Many others are about 8 W.

I have the TetraTec 5 W on my 55 gallon. I can't say for sure if it is or isn't working, but I can say that I haven't had the algal blooms--that I was having problems with before I installed it--any more. Also, no bacterial blooms.

Coralife makes a very nice UV. They range from 9-36 watts!

how do you determine what wattage you need for a certain size tank ?
