Second season with the pool. Last year went well, learned a lot here and didn't have any major problems.
This year, I'm considering adding Borates to improve the swimming "experience", but have few questions:
I live in the Dallas area and the fill water TA is normally 110 to 120. Last year, I tried to get the TA down but could only get to about 90 because of having to add so much water due to evaporation. After the winter, it's back to around 120. FYI, for aeration, I've got a SWG and spillover spa. I also turned the PRV discharge towards the surface on the hose for the pressure cleaner to get a little more.
Other chemistry looks good and I maintain CSI between +0.1 and -0.2 (reduced some scaling in the pool).
1. Has anyone been successful in getting TA down to 60-80 and keeping it there with the high evaporation and elevated TA in the fill water? If so, any suggestions or tricks?
2. Is it really necessary to get the TA down before I add borates? I know it will be harder to lower TA after borates, but is it really that necessary?
3. For pH control, I understand that borates will not reduce the overall amount of acid used during a season, it just changes from adding a little bit frequently, to adding a higher amount less frequently - i.e. pH drifts up slower, but requires more acid to bring it back down. Is this correct?
Thanks in advance,
