I performed a 40% water change on 7/25. After which my calcium level was 400mg/l.
I then dosed 5tsp of calcium chloride that evening, and that brought my calcium level to 480mg/l and my Alk to 10.2dKH.
From that point on I continued to dose 1.75tsp of Ca Chloride each evening to account for my average daily drop of 14mg/l. I dosed on 7/26, 7/27, and 7/28. On 7/29 I tested my Calcium and it was 480mg/l. Alk was 10 dKH. Since then I have not dosed any calcium, and have been topping off with R.O. water daily. As of today, 8/9, my calcium is still at 480mg/l. No livestock have died and I have new light coraline growth on my glass. What gives??
