I'm a new pool owner and just really want a little reassurance on my test results. I use th TF 100 test kit. I am a little concerned with the high TA and low Ca.
Ca 50 or 75
It seems the ph slowly keeps rising in my pool. I have had no problems this year except for metal staining and did refills for high cya due to old house owners using pucks. Should I add acid to lower the TA? Thanks guys!
