Marty, if you really want to try out a UV sterilizer, I have one. Its a 15W and you just need to hook it up to a powerhead. I think I had it attached to a mj1200. let me know, you can have it if you pay shipping. The sterilizer will only kill those bacteria that are in the water column so if your water is really clear its doubtful that the UV will really make much of a difference IMO
