I'm thinking the same thing, just get rid of the controller. The benefit of the controller (I thought) was as a safety net. I could crank the CO2 to raise the saturation quickly and rely on the controller to cut it off at the (safe) set point. If I abandon the controller, what's the best way to maximize the CO2 levels while keeping a safe level? I currently only supply CO2 in the photo period and turn it off at night. The tank is a 150 gallon with 8 adult discus, 4 young rams, 6 small coreys and 2 rainbowfish. This seems like a low fish load to me and discus typically are from low oxygenated water. The KH is 4 and I inget CO2 to a Ph of 6.7 (via the controller). What would be a safe BPS into my AM 1000 reactor to achieve a PH of 6.7?
Thanks to all!
