I recently bought a house with a 28 year old in-ground plaster pool. The pool hadn't been neglected, but it hadn't been kept up very well either. I recently cleaned up the pool tile (glass bead blaster), cleared up the slightly green and cloudy water (lots of granular shock and chlorine pucks in 3 floating chlorinaters). I also recently installed a new Pentair VS pump, Hayward salt system, booster pump and replaced all grids in the DE filter. I now have the water looking crystal clear, but it's not in balance. I live in the country and have a private well. My pool has an auto fill and it is connected to the soft water system in the house, so any fill water is after the water softener. With the old test kit I had, I knew the ph was high (8.0) and the TA was high (400) but that's all I knew. Over the past two weeks I have added 10 gal of acid and have also aerated the water off and on. Today I got my new test kit and have the following results to report.
Water temp 68 deg
For reference, below is what my tap water in the house is. Same source that fills the pool.
When I installed the salt system the FC was 8 due to the floating pucks and shock. I originally had the salt system set at 30% but shut it off last week to bring the chlorine down. So based on all of this, where do I go from here to get my pool in balance?
Thanks in advance for any and all help.
