Pool Volume 16,000/In ground plaster/Inline Chlorinator. I used 32 oz of 6% chlorine yesterday and had Leslie's test water this morning. Of course, they said to drain pool 80% and/or replaster. We've never had these issues before and pool is 14 years old in full TX sun all day. They stated we should only use 1-2 tablets in chlorinator at a time, which may be the issue since we've always filled it and ran it at 4 for 9-10 hours a day.
I've heard you can add lye to help lower CYA, is this safe? If we add overnight with pump running will it be OK to swim next day?
