So I am running Kalk in my ato and have been for almost 2 months now. I am running it pretty low with only 1 teaspoon per gallon which keeps my Alk very stable doesn't deviate from 9.9 more than ~.1 so I am very pleased with this. On the other hand my Cal consumption is not as high as the Alk which makes it climb about 15 ppm everyday. I don't know if this is a problem or not. After my weekly WC it typically is right about 400 ppm and right now it tested at 465, so steadily climbs until the WC puts it back in check. My concern is, I don't know how much of a problem the Calcium creeping up like this may or may not cause. Is it an issue having the Cal raise like this as opposed to it being steady like my Alk is? I know it will be asked: Alk 9.9 Cal 465 Mag 1395 PH 8.6 Temp 79 Nitrate .02 Phosphate 0 No other changes really. I have been working on stability over anything else recently due to the stability issues I had a couple months back which set back most of my coral. All my SPS are doing great at the moment. PE is really coming back and even on some frags that I hadn't seen PE on before, and a few of my frags had lost a lot of color as well which is beginning to come back, they are fluorescing under actinic again, which I am pretty excited about but I want to make sure if this is a problem that it gets corrected sooner rather than later. I appreciate any help 3Reef can give me and TIA!
