That most impressive, but a couple of questions. Did you do that setup bcuz of quantity purposes or convenience? I have a 20gal reservoir with a recirculating systems suppling a 4x4 tray. I change the water & nuits once a week, I know a little excess but seems to work. But only real problem I have is that my Ph level rises over time.
BudLuv420 Reviewed by BudLuv420 on . My Ph controller Tired of constantly checking your Ph? well this unit will do it all. First pic is the brains, next is the relay/terminal box. This unit is going to run two Ph pumps, one up,one down and the GH three part nuits. Five pumps total. It also has three water level sensors, and controls fresh water valve, controls circulation pump and two irrigation pumps. Adds nuits back to set EC and maintains it then adjusts Ph to set point and corrects as it drifts. I still have a little wiring and pump Rating: 5
