First off I want to say thanks in advance. I just bought a house with a pool so I am new to everything. Here are my readings from my kit. I am using 3" chlorine tablets. My pool has been open for a week now. I took these tests before running my filter for the day. My filter has been off for about 12 hours. Will the results change after running my filter for say 4-5 hours?
Ph is 7.5
FC is 5
Cc is 0
Ta is 170
Cya over 100 ( did test twice).
Looks to me my cya is really high and at the point I should drain and add water. Any help or suggestions would be greatly appreciated!
