Well the big day is coming soon, I’m diving in to setting up my 150 g and 39g sump. Do I put a refugium with sand, mud, chaeto and rocks with copepods from algae barn into the sump or just rock and algae? Doing the plumbing on June 10th,11th. Getting help from Aquatic realmz in Milwaukee those two days here’s some photos of my reserve tanks for salt water and rodi water.
