more flow?

[brandon0350]

do you think i need more flow? 90 cube 30x30x24. i have a 400gph return and 4 seio 620s in the corners pointing toward the center so all the flow is coliding. its very chaotic but im not sure if its enough? do you think i should go up to 820s?

I think it depends on the size and amount of corals in your tank. Lately the trend is to have 100x turnover for a tank full of frags. This amount of flow probably isn't needed imo.

I am not a lots-of-flow honk, but I do think that you need a little more.
