570 GPH good for a 29?

I currently have a 170GPH power head and a 400 GPH Koralia 1 power head(the ones that kind of look like fans)
before I added the Koralia I had a diatom problem, I put it in and they have decreased a good amount, I still have them behind rocks and on some.
Do you think I have anough flow?
Its a standard 29

20 times an hour is fine for sps, lps, anything you want to keep. I have enough pumps to turn my tank over about 35 times an hour, and that can be to much flow for some corals.

Are you also counting the GPH of your filter and/or protein skimmer? I have almost 40 times flow in my 29. No SPS and not too much flow. No complaints from my corals. They have told me they are very happy.

No SPS corals and dont plan on it, Ive tried them but being a student and working I dont have time to take care of those type corals. And im not counting any of the filters.
Just the 2 power heads.
I may go buy another Koralia pump and use the 170 GPH for something else.
So I would be 800GPH. Not to much is it?

Your flow includes all water movement so you should count your PS and Filter also. Like I mentioned I have 1155 gph in my 29 (counting filter and ps).

Not enough IMO. a 170gph conventional powerhead is pretty weak and 400gph of prop flow is also weak as well. 570gph of conventional powerheads would be enough (thats about two maxijet 1200's minus a negligable 30gph or almost 20x turnover). Now having propeller style powerheads after years of conventional powerheads my rule of thumb is to double what ever flow is desirable with conventional powerheads. I would like 600gph minimum on a 29g with conventional powerheads (20x turnover) so with propeller style powerheads I'd do 1200gph (or three koralia 1's). the dispersed flow allows alot of it without beating things up so take advantage of it. I have 70x turnover in my 30g with no ill effects or anything blowing around (1400gph maxijet 400/sureflow kit, 400gph koralia 1 and 300gph flare output from return pump. pump is actually 600gph so 300gph is a guestimate). basically the more the better as long as your substrate and livestock dont have problems tolerating it.

alright, I look into another powerhead, not another koralia, thats stronger.
thanks
