Hello! I have the TF-100 kit and here is my reading (this is my second week using daily/weekly readings from the kit)
PH= my daily test shows it at 7.8 (I'm still sort of confused on this one - is the daily test how I read the PH, or am I missing something?)
My water is crystal clear
I know my CYA is high, and I've been told draining half the pool can help with that. If I don't drain half the pool, is the worst case scenario that I have to keep adding chlorine on an almost daily basis? If I do drain half the pool, will that help lower the TA a bit?
Also, the pool store owner I was working with (who I'm not seeing anymore) told me that I should have my TA above average, or else my pool heater will be ruined (copper coil heater). Is that true?
