Our pool is 4 years old and we just had to drain and refill due to very high CYA. We learned a valuable lesson there and I am now using TFP to maintain the pool. We refilled the pool 4/21. I bought liquid stabilizer and added that 4/29. I know it takes a while to be reflected on the test. Here were my results today::
I added chlorine (liquid) today, but my questions are about the other numbers.
Will the CYA continue to go up? I added a full bottle about 6 days ago.
Do I need to bring the TA down? I have been adding Muriatic Acid, but the pH hasn't gone below 7.5 (I am basing this on Pool Math:To lower TA you reduce pH to 7.0-7.2 with acid and then aerate to increase pH.) Keep adding?
Should I be concerned about CH at 125?
We have been maintaining our pool since the beginning, but apparently not very well (see above, drain/refill!) I want to do it right this time and avoid future problems as well as unnecessary $$$$ at the pool store! Thanks for this great resource! I have learned so much already!
