Help with my Uv sterilizer

[reedwithE&Y]

I have a wave maker and my hob filter & now I have my ub stent question is, is it better in the middle of the tank or more at the surface. And can it be to much flow for my clownfish

i dont think it can be too much flow for your fish. @tbrown?

It can be but it's unlikely. I'm running 3 x 2100 gph gyres and powerheads at 45% and a 800 gph return in a 70 gallon reef.
