Alk / Calcium / PH

[tim_12]

I just added some zoos to my tank the other day and I also noticed that my coraline was turning white, so I figured it was about time I tested for calcium and alkalinity. I bought the test kits today (Nutrafin) and my calcium tested at 320, PH at 8.1 and alkalinity at 150ppm. I also tested general hardness and stopped when it reached over 400ppm. Shouldnt GH be much lower than this? Does this mean my magnesium levels are low / high? Any tips on getting my levels back to normal? :help:

judging by your Ca levels it sounds like your are using some salt like instant ocean? Did you recently switch it it? that may be why your coraline suddenly turned white. If you switched form another type of salt with more Ca. Ca should be between 400-440. To raise it you can drip products such as kent turbo calcium.
