I currently have a 75 gallon dt with a 20 long sump. I have a mag7 as a return pump. Both the overflow and the return have ball valves for control. The return is 3/4" and overflow is 1". There are 3 sections one being 11x10 with baffles being 9". I want to get a reef octopus but it says that optimal sump water level depth is 5.5". Is there a way to lower the sump level to accommodate new skimmer without re-doing the baffles?
