What gph are you running through your G.A.C.???

Some articles I've been reading recently are recommending what seems to be extremely low (like 10 gph) flow rates for G.A.C. What's typically used, for gph, by us reefers??? I know mine is at least 5 times that. Just curious what others run.

I'm probably running about 75 gph. The total flow does depend on how broadly the flow is spread. As long as the carbon isn't getting ground up, the flow rate is likely fine.

OK thanks.

I have mine in a Phosban reactor 2/3 full and fed by a MJ 400 . It is probably in the 60-80 GPH range if I had to guess. The key is don't agitate it so much it tumbles and erodes to dust. Carbon is very soft and wears away quickly.

My pump is rated at 100gph and it's pushing it up 18", so I'm guessing about 75?
