We just moved to a new home with an existing pool. The water was clear, but the CYA was 100+ so I did a complete drain and refill last week. Here are my current numbers using a TF-100..... Note I have not added any chemicals in 24 hours and I'm in the process of bringing the TA down from an initial test of 180. Should I deal with the CH as well? Thanks.
