Are you talking about water changes? or water turnover (flow) in your tank?

Sorry, should have been more clear. Water Turnover (Flow) in the tank.

Thanks.

Depends on what you want to keep, if you have a fish only or fish only with live rock (fowlr) setup then you can get by with 10x turnover per hour, with a reef setup, 20x-30x turnover per hour is right about where you want to aim. Hope this helps.

Wow that means 1000 to 1500 gph in my tank. How am i supposed to achieve that? I have a ehiem 2215 that pumps about 200gph and a maxijet 400 that does 109 gph. I want to get another powerhead but there is no way I'll get to 1000gph.

Any suggestions?
Thx
