Water movement question

Yes, throw in the two Maxijet 1200s. I have a setup similar to yours minus the fluval (which I sold, cuz it's crap) and I would say the two powerheads are mandatory. I might even throw in a MJ900 tonight (blowing against the front glass) cuz the sun coral I bought yesterday seems to open better with more flow. Another thing to think about is, with such a high bioload and insufficient flow, cyano might be knocking at your door.

IMO, the fluval might be sufficient for a fish only setup, but it's useless in a reef. Canister filters build up nitrates as well if I'm not mistaken. And changing the cartridges wasn't much fun either, at least for the 403 model.

How long have you had the 4 different clowns in the same tank for? Do they actually get along?
