I have taken the advice to SLAM the pool and deal with the staining end of season. I have ordered the TFT-100 test kit as our kit did not have the FAS-DPD or CYA tests. TFP indicates I need to raise my PH up before doing so. This a.m.'s tests were PH 7.2 and TA 90 (Chlorine <.3). I've read that PH should be 7.5 - 7.6 and TA 60 -80.
I want to get this right and read many threads but am so confused as to what the proper steps are to adjust the PH and AK and the products to use.
Also - read about adding DE to sand filter but hubby believes it is a sealed unit? Does that make sense ???
And while I'm at it - still have some slight pinkish algae on pool walls - can we swim???
Thanks and a Happy and Safe 4th to all!
