need some help. I live in Baltimore, MD and its about that time to close my pool. I started to try borax last Sunday. Added about 50 pounds but the AK is at 210 and PH is stillbeloe 6.8. I had used bleach before, clorox. Any ideas, should I return to soda ash.
If I ad muratice acid the PH will drop further, no?
BTW the pool is crystal clear.
