Hi everyone, it's been a long time. I'm converting my fowlr tank over to reef, gonna be askin a lot of advice in near future. First, what is a good GPH flow rate? I have a 125 display w/ a 75 sump/fuge. Currently running a coralife skimmer in sump, 220 model think it is and I have 2 return pumps, one is a mag-7, the other is a maxi-jet, w/ head height both should be averaging 400-500 gph. One feeds the fuge so maybe only half is getting back to the display, I feel I need more turn around. Any advise will be well taken. TY in advance.
