K total newbie question. Just getting things ready to set up. Have a 100gal RR (60") and am planning a 39 gal refugium sump under cabinet with LR LS and macro algae and mangrove. Tank is drilled with one inch bulkheads. So question is: what GPH pump should I be running with this setup?? Most of the stuff that I have read has said anywhere from a 4 times to 100 times turnover. HELP????
