I started with the two part additives, but consistantly struggled with keeping my Ca
levels up. I also found that I consistantly needed to add additional Ca
in order to stay balanced. It got to the point where I was having to dose at nearly double the maximum daily recommendation and I didn't want to do that all at once. This required dosing 2x per day so as not to shock the system. Too much work.
Finally, I gave up on the two part additives and went to Kalk
. Now, I'm balanced Ca
all the time. Ca
levels rose to just over 400 and are stable. I'm currently mixing Kalk
at only 7 tsp/5 gal
and I drip 24hrs/day to match evaporation.
I'm very happy with Kalk
. But I would agree that it is a pain to mix and drip. The problem was that the 2 part additives became more painful than Kalk
