How much is to much flow (1 Viewer)

[NarnyTheGreat]

I am wondering if my power heads would be to much for the fish I intend to keep (2 marine bettas). I have 2 hydro koralia 4's 1200 gph power heads on a 60 gallon square tank.

Do you all think thats to much? Should I lower the flow? If it were a long tank I would say it was fine but with the square IDK. If it is to much what size should I shoot for?

I would start with one and add the other if it seems to have dead spots. When we had our 60 cube, we had to upgrade to two but that was due to placement of the rockwork. Just play around with it a bit and see.
