Powerhead

[66chuck]

After two weeks of trying to stop my powerheads from spitting millions of micro bubbles, I concede defeat. I'm going to buy new ones. How many GPH turnover is recommended for a 125 FOWLR?

GPH 2500 to 3125. I know Hydor Koralia 4 do 1200GPH so two plus your HOB filter then see what you have. I have two on mine plus a 350 GPH then a skimmer with two 250 GPH and my HOB filter 350 GPH. So I have 3600 GPH

I would go with the koralia's. I have a 4 and 3 in my 120 and there is plenty of flow. I also have a rio, 3 maxi jets. JMO
