My husband and I had a pool w/spa built after living in our new home in SWFL for one year. We have never had a pool before and know very little (I mean nothing) about pool chemistry. The pool builder took care of it for the first month with chlorine and minimal brushing of the new plaster, and told us to start with a pool service. We are having trouble with the PH and scale and our pool guy thinks we are “picky”. The builder came and added 4 gal of acid to lower the PH and get the scale off, but both times the pool service has come they have added liquid chlorine that has dissipated within a couple of days. The pool is supposed to get converted to salt next week (by the builder). We are totally confused and clueless.
