Here is my start. The short pipe that drops down a bit has a threaded adapter for water changes, it doubles to fill bags for transporting corals or to get water for testing. I still have to add the shutoff on the display fuge drain line (back left drain line). The display fuge is a 20 gallon tank not yet moved.
ill post pictures of my setup tomorrow after i upgrade my srtup. it consist of a 90, a 50 gallon sump, im adding a 125, and 2 90 gallon sumps. its all controlled by one panworld pump and theres an APEX on the way
