I've been testing my pool and the pH and TA has been high. I have added muriatic acid for 5 days in a row. I was wondering if this was normal for a newly filled pool. I have a Pentair (Rainbow Lifeguard) Pool and Spa Test Kit. I just started writing down the test results yesterday.
Chlorine 3+ (my test only goes to 3)
Acid Demand 6 drops added 2 cups & 1oz acid
Acid Demand 4
Do you think my results would be off if the test was old? I have new strips and they show high on pH & TA, but they are strips.
