One question, you got a massive ca rx, was the kal reactor necessary?
I use the Kalk Reactor in line with my ATO. It is used to stabilize my PH. It is programmed to turn on for 5 minutes every hour when the float switch is down and the PH is < than 8.3. As you can see I have perfect PH. PH2 is the probe inside of the carx reactor. It is said that effluent from a carx lowers PH. With Kalk dosing I have not had this issue. This picture was taken at 3 AM when PH is typically at its low point.
