Water Flow For A 75

[aaronlp]

I Currently have 2 Koralia 1050's i am looking to add 2 more powerheads or replace them i have been looking at the Koralia Magnum 7(2700gph) is this overkill. If so what would anyone recomend for good flow?

Thanks!

I used a K3 and a K4 in the 75 I just tore down. There seemed to be plenty of flow.
