Hey everyone going to try to figure out this big monster of a reef website. So what better way than to post about my tank system. I have a 120 and a 35ish gallon tank (DIY tank I built from a broken 40 breeder) both plumbed into a 100 gallon sump but only has around 60 gallons running. Everything I do mostly revolves around DIY because I like the challenge and pride of making something custom for myself. Shoot me any questions you might have in the process of trying to figure out my 2 part dosing and how to figure out my automated dosing rate.
