Hi everyone...new here and just got a 300 gallon acrylic tank used for a pretty cheap price. The original owner had it setup as a reef tank so he has holes in the back panel for bulkheads for better water movement behind his reef. I've never really seen how this is all plumbed with all the holes...just wondering if anyone does something similar and can show me a pic of how these are all plumbed. There are about 14 holes in the back about 1.5" in diameter. Thanks....oh and here is a pic so you know what i'm talking about.
