The Alch in my pool has been sky high since we had a new liner put in 3 months ago. I can not for there life of me bring it down to read on the stick.I had a computer read out of my chemicals and i believe it said 297 it also told me to add 2 lbs of a Alch/ph reducer. I did it yesterday at 11 am and today with the pump running all night at 3pm its still the same color on the stick. Any suggestions.The water WAS clear till last week here is no algae in the pool according to the 4 algae tests it done its just dirty and murky.
