My plaster pool is 13 -14 years old. I am getting it replastered in a month or two, so don't want to empty and refill at this point, so need some help.
I attempted a slam over the past week, and now letting my chlorine come down. I am out of the R0871 so can't get exact reading at this point, but smaller test shows FC over 5. (I think target is 7-9 at this level)
CYA is about 80 (yikes).
My questions are these: With these high levels of CYA I know I need high FC. However, does FC that high make the PH test inaccurate? PH (after slam) currently showing 7.8 and I added acid to bring down to 7.2, but not sure that test was even correct?
How do I keep it swim safe and algae clear until I get it replastered? Do I need to do the FC drop test to keep it accurate? (ordering test refills)
Going on vacation and need to leave my daughter very explicit directions. Thanks for the help.
