I have a 72 gallon reef and I just traded out two MJ1200's (295 gph each) for two Koralia 2's (which may be up for sale soon so I can get a pair of 3's). The Koralia's (600 gph each) should be doubling my flow, but the fish seem to be considerably labored in their breathing, which greatly concerns me. Any ideas or input would be greatly appreciated.
Thank you,
Adam
