Ok well first off I'm new. Loving all the stuff you guys are doing on here. One thing I'm not quite getting is the sump I understand the purpose and some what what to put in it but was wondering the prosses is and what compartments to have in it for a fresh water tank? big question how does it work In conjunction with my filter or as a a oth filtration device? Also how would a attach it to my tank? What's a good zize for a rule of thumb? Sorry for a noob question but I want to do the best I can for my fish and figure out how I big and what to use in it for when I go to build my new tank
