Kalk amount increased...

[Untamed12]

I just wanted to provide you with some follow up on something you thought I should do. It has been about 4 weeks since your advice that I should increase my Kalk input to overcome dropping Alk.

Over that time, I have steadily increased the Kalk amount such that I am now dosing 44% more.

So far, the Ca levels have not changed. I'm no longer having to add Alk supplement, and the Alk is generally higher than before.

Current measures: Ca: 360ppm; Alk: 2.65meq

So far, so good. Thanks!

That's as expected. The calcium can't rise much with a balanced calcium and alkalinity additive because the alkalinity would go way too high. I'd boost the calcium one time with calcium chloride. This article and calculator should help:
