I used the salifert test for Alkalinity/carbonate hardness and I ended up using all .8 ml of the solution in order to get a reading, meaning that I have a 15.7 kh value? I feel like this is insanely high and I am unsure of how to lower it. Any help would be good, thank you! I do not use RODI water if that is of any help. I also have about 6-10 sps corals and 2 lps in my tank, but only now have they started to suffer from this supposed fluctuation, as before, the lps were doing perfectly fine and branching out. I also double checked with the API Reef Master test kit for KH and the readings I got were 12 dKH and 214.8 ppm KH.
