Ive been working on this for a few years now. It started with a 270 gallon plywood sump connecting a 40 breeder, 40 long and 30 gallon. I later added a 65 gallon, a 100 gallon Rubbermaid cryptic fuge, a 20 gallon holding an ATS,,and am currently adding a 90 gallon. Long term plans include a couple more small tanks,,amd a 10' plywood build on the system. All current tanks a lit with rapid DIY LED's, skimming is a MTC, HSA 1000. An apex 2016 automates the system for me, amd I have a fuge with a kessil360 and a biopellet reactor on the system also. I am setting up 2 DOS units to deliver ATI essentials to the system.
