Hello, just uncovered and started the processes of cleaning up the pool after a brutal winter. The winter was spent learning here. We are a new homeowner as of September 2013 with an old but nice in ground pool. The previous owner had a new liner put in may 2013 obviously with a total fill. The prior owner just ran the pump 24/7 with the SWG set at about 60%. The water was crystal clear so for the few weeks we could use the pool I did not mess with it.
I tested our water today with my new Taylor 2006 kit.
Total Alk - 80
Calcium hardness 80
Clearly I need some CYA in this pool and once it warms we will add the correct amount. We did start filtering today with the pump running. The liner paperwork I have says to avoid low ph as this can wrinkle the liner. I added baking soda and now the Ph is in the 7.4-7.6 range. Total alkalinity bumped to 90.
The liner warranty suggests a total alkalinity of 100-150 TFP suggests with a SWG for a vinyl pool 60-80?
What is the best path? If I do not want to increase TA anymore when my Ph dips down then either Borax or sodium carbonate would be better options if I understand everything correctly
