Pool is 2 years old. 29k gallons. Salt water. TA = 70, pH keeps going 7.8 or higher. Added MA to lower to 7.2 measured 24 hrs later. 36 hrs later back up to 7.8.
I'm trying to get ready for an Ascorbic acid treatment to get rid of some stains. CYA = 0. I get a certain amount of very fine gravel that seeps up above the tiles, especially at the skimmer. I think it may have iron content because it stains if left there for very long. I plan to seal the offending areas with silicone sealer.
The chlorine generator was turned off for the past 48 hours. Any ideas would be greatly appreciated.
