ok, I use my ACIII to pump my kalkwasser at 8.13. after messing around with the sump fan speed and the lower limit ph I have gotten it to about match evaporation at 5 gal ~3.5 days. currently I am adding iodine to the kalkwasser. is there any reason I can not add Mg to the kalkwasser. ie: test, do the chart, add X amount of mg to kalkwasser, test again in 3 days? or can I just dump it in my sump..
