Can anybody help explain where my calcium test is going sour in my hot tub? I'm hoping that I just have too much bromine, but I don't ever recall having an issue with a high range level like this before. Unfortunately I'm not use to dealing with bromine yet.
Temperature: 100 F
New water as about 2 weeks. Have not used any MPS so far. The tricky part is that it's not actually turning blue after adding R-011L, it stays clear.
