I have an aqualifter feeding my kalk reactor on a timer. It goes on at night. I can have it add kalk water anytime I want. I have my top off water controlled with a JBJ ATO unit. My ATO draws water from a 35gal barrel next to the tank into the sump. My aqualifter draws water from the same barrel and into the kalk rector. The output from the kalk reactor is in my DT. It drips in the return flow.
