ok i'm redoing my 20L and upgading my pumps . here is what im planning. the ank is a 20L with a 20h sump/fuge. for my return im thinking an ocean runner 2500 (650 gph) throuhg a scwd. right now the return is a mag 7 through a scwd.

ok for the closed loop im getting an om squirt. i dont know if i should use an ocean runner 2500(650 gph) or a 3500(900 gph). would that be to much flow for the tank. right now its just zoos and lps but id really like to keep some sps. here is an old thread on my tank. it pretty much the same.

just a bit. 65x to 75x turnover. You don't have substrate i'm guessing. =)
