I have a 10 gallon ATO container that I used to supplement Kalk with 2 tsp to 1 gallon RODI ratio for over a year. Two months ago I stopped the Kalk dosing and using the pure RODI as ATO. But I notice there are huge layer of Kalk powder/deposit at the bottom, probably an inch thick or more. And every time I fill my RODI water into that container I get milky cloudy water.
Is there a way to check if the water has no kalk dissolved? I can confirm that I didn't see PH spike now as before when I was still dosing kalk. My PH stays 8~7.87 through out the day without adding kalk to top off water, as before with kalk top off I usually got PH 8.2 or higher value.
And is it necessary to clean the kalk deposit inside ATO container? It will be a pain to take that tall and thin container out, and it is more pain to clean it through the small opening. But the thick deposit dose look scary from outside...
