Filteration Order?

[CP_ThunderGod]

If I wanted to do it perfectly...

Water would travel from the overflow box through a prefilter then skimmer, bioballs, then finally through a uv steralizer and return from the steralizer into the tank?

Is that the best way?

Should I put the steralizer on the return pump or will it be too powerful and diminish the kill rate? or where should I place the intake and output of the steralizer?

I wanted to use a powerful pump to branch off to 2 or three and run the returns on the top of the water.

The sterilizer should definitely not be put on the intake or return of the filter. You should have a separate pump on the sterilizer, preferable on the lower end of the recommended gph for your particular sterilizer.

Yep

I also agree with Guage, unless the UV sterilizer is huge, it will not have a very efficient kill rate with that much water going through it.
