I have been using an apex pH module & probe to try and determine when my Kalk reactor’s was becoming un-saturated and would need refilling. According the the advice given, a better indicator to use would be my apex conductivity probe. As an experiment, I have now replaced the pH probe with the apex conductivity probe and in addition, guessing I should change the “Range” setting in the salinity module settings to “High (0-85mS/cm)”
After cleaning out the reactor and adding fresh RO water and 2 cups of Kalk powder, then inserting my apex conductivity probe, the reading now shows 19.8 mS/cm. According to this thread, it seems I should be seeing more like 10 mS/cm??
Can anybody help me with an idea as how far to gauge before I should be upping my Kalk reactor’s concentration with the help of the new readings?
