Pool water is clear and FC drops 3-4 ppm every 2 days.
Lately we had a lot of rain and the jet was pointed up so I think the water was aerated.
Either way, the pH has been fluctuating and testing is producing a range of results. TA was 120 for the longest time and is now shoing 90-100.
Should I add baking soda to raise TA? Borax to raise pH (sometimes tests at 7.0, sometimes at 7.8).
Last question: is CYA f 30 sufficient or should I make it higher.
