I am a long time pool owner (since 1990) but just started doing my own testing this week. One of my friends owned a local pool store which I utilized for testing, they used a drop/color based system which provided consistent results so I utilized them for many years. They sold the pool store and the new owners switched to a test strip based system, immediately I started to see issues with the results and couldn't trust the numbers so I decided to purchase a TF-100 and perform my own testing.
I received my test kit on Thursday and tested that day, I then performed another round of testing today, other than CYA, which I am raising, the results were very consistent between the two rounds of testing.
PH 7.2 (Did not plan to adjust as I have a SWG and know this will rise on its own)
CYA 45 (started out at <20, added 8 lbs of CYA and waiting a week to see where it lands)
The water is clear and I'm not having any issues holding chlorine (supplementing with 12.5% liquid until the CYA gets high enough for the SWG to keep up).
My questions are on the TA, do I need to go after it now to get to the recommended 60-80 for a SWG equipped pool or just let it come down with the required acid additions over the summer? What is the potential issue if I leave it at the present value?
