whats you flow?

As to what is in there for corals;
9 SPS large colonies, 12 larger branching SPS frags, 3 types of zoa colonies, riccordia colony, Torch colony, Frogspawn colony, Xienia colony 3 GSP colonies.
So a mix of everything, and now I come to realize why i have been having to up my dosing of Calcium and DKH consistantly.
The tank again,
around 125 gallon, 4 k4's (4800), and a Mag 18 return (1800) so grand total of 6600 gph. I assume the mag losses around 600gph due to plumbing so 6000 gph (around 48 x per hour) when everything is running (around 3-4 hours a day) and 3600 gph (around 28.8 x per hour) when the wavemaker is turning 2 K4s on and the other 2 off in a 45 second rotating cycle.
