I have a small biocube 14 running about 7 years and I've got a fire shrimp I've got two clowns and a lot of different coral and most of the coral looks very good but I can't seem to keep my KH up it's usually about 7:00 or just below and I just started dosing Kalkwasser in the ATO reservoir beginning of the week. Calcium is staying at 4:30 and everything else is good magnesium etc but the KH just doesn't seem to stay up there any suggestions?

So with the kalkwasser being used it is below 7 dKH?
How much solid calcium hydroxide in how much fresh water?
