Im in the process of hooking the apex system up and need advice on the ato portion of it. I bought the breakout box today and am wanting to order my float switches but am unsure on the number I need. I know I will at least need on in the sump to measure when the water level drops. Will I also need on in my ATO reservoir? I will be using kalk through the top off but will only use it when the pH is below a set parameter so I will also need help with programming so that one pump will top off with fresh water when needed and the other will top off with kalk when needed. What would you recommend? Do I need a switch for low water levels and high levels?
