Hello everyone, Iím new to the hobby currently with a 37 gallon gallon tank with only live rock. Soon I want to upgrade to a 100+ gallon tank. Iíve been doing some research on sumps and this is my plan and I want your opinion on it.... 30 gallon sump, with a sediment filter that I would attach to the main line, a small protein skimmer in the next chamber , and a refugium. I believe if I was custom making a sump I would need 3 or 4 chambers? one for each item listed and a small section for a return pump?, also what about a overflow area?
