ok so during the holiday, I recalibrated my ph monitor because it was reading way high. I did this like 3 times and now it reads that my ph is very low 7.8, use a test kit to confirm this. I think its because I have been dosing Kent turbo calcium for a 2 months, and its been lowering my PH slowly. just recently I lost an SPS, so I decided to check everything. I am now using kent supper buff, but I wanted to hear what you guys use.
