is a PIA! I mix about 5 gallons at a time. I don't saturate my kalk
mix, just use the recommended 1 tspn per gallon. Depending on your calcium consumption, you might go up to 2 tspn per gallon of RO
water. I fill a 5 gallon container with 5 tspns of kalkwasser, stir with a plastic spatula (must be non-metallic), cover the container tightly or carbon dioxide can render the solution useless, leave overnight. The next day, sometimes two, I lift the 5 gallon bucket onto something higher & siphon the solution inbetween the top layer skin that forms and the bottom sediment into another 5 gallon bucket, fill my 2.5 gallon aqua dose and cover the remaining. This last me for about 8 days (2 refills on the aqua dose). I just get the next batch ready after the second fill.
I drip my kalk
via a gravity dip line (Kent aqua dose). I feel that topping off evaporation even at night raises the PH
Even with the kalk
, I find that I still need to do the two part additive to keep levels in check. I use C-Balance two part.
