Even when I have put a gallon of muraictic acid in the 24,000 pool in the last two days? ph was 8.0 and i assumed it would go to 7.4 or so but it was 8.3 a few minutes ago. chlorine is also up even though i have not shocked in several days. i do have 3" tablets and 1-2 have disolved in the last 5 days.
