I have been trying to balance my TA and PH. PH goes high quickly, and I thought that TA was too low at about 50. Now trying to balance a little at a time. But - when I use my Taylor PH drops (which are just about gone), I get a PH reading of 7.4. When I use the new bottle I bought to replace (All Clear brand), it shows the PH off the chart! How do I know what reading to believe? I could believe a variance, but it is huge, and I am confused.
Originally my TA was about 50, I thought that might be contributing to my PH spiking daily, so I raised it. It's currently about 90, but last time I got it up to 90, it dropped back down again due to having to add acid for my high PH. Dropped over the course of a week or so.
