I wanted to get some comparison data from others on the amount of Kalk powder others are using in say a 1 week period of time?
Granted I have a large volume system (call it 600g), but I seem to be dumping in lots of Kalk and still not driving my PH, Alk, or Ca off the scale. I am dumping in about 6-8 tbls every other day or so (when I see PH dropping near or below 8.0). When PH is 8.1+, Ca is sitting around 475, and Dkh at 10-11.
What are other's Kalk usage and what's your water volume and Ca demand levels?
Thx - Steve
