I have seen other threads saying that Polyquat 60 is not necessary. Is there ANY benefit to it? Is it just not cost effective or is there really no benefit?
My plaster was done in June. I am still using about 1/2 gal of acid each week to keep pH in check. Will this be a problem over the winter? Should I drop it to 7.0 before covering? Do I need to lift the cover and check it every couple weeks? If I do nothing, will it continue to rise and be extremely high in April?
