GPH Rate for 29g Biocube?

Just wondering how many gph I should be pumping with my powerheads. Right now I have a total of 418gph moving through the tank with the biocube filter and the powerhead I am using. Should I increase this? If so how much

Thank you!!

 

What will be in the tank? Mixed reef? SPS dominate? LPS? Soft coral? or a FOWLR (fish only with live rock)?

What you have now gives you a bit over 19x turnover when you consider the amount of water probably displaced by rock. My 29g display tank only holds about 23 gallons of water. You may want to add one koralia nano (425 or 240). That should put you at 30(for soft LPS corals) - 40 (lps dominate) times turnover.

In my 29g I have 3 Koralis 425 powerheads. That's 1275gph plus my return pump will add another 400 or so. I wanted high flow in my tank, so that's why my turnover rate is 75x. But you don't need that much if sps dominate reef you could go more if you really wnated to though). I may dial the return flow down some.

 

This should help...Basics of Flow

 

Thanks guys this helped. I went to the store and picked up a Aqueon 500 so it makes my tank around 920gph which I guess would be 30x. Once I remove the Biocube bio-balls, add a cheap reflector light to the back and throw in some macroalgae I should be in real real nice shape

 

That sounds great. Just be sure you remove the bio-balls slowly (a little bit at a time over a few weeks) as not to effect the water parameters too quickly.

 

I've been doing that slowly and throwing them in a pod tub i've made. they really get pretty nasty and slimey
