Still having **** with my pool and pool builder. In late November, PB did an acid bath because they never did one at start up. There were a few stains that he wanted to clean up etc. After the acid bath we were amazed at how good the plaster looked and understood why PB wanted to clean it as he couldn't show this pool to other clients with the plaster looking the way it did before. The plaster is a mediterranean designer series from Noble tile in the DFW area.
Within about two weeks, plaster was beginning to become patchy white, very inconsistent, actually looked worse than before. Of course pool builder tried to blame everything on me. I test my water at least once a week no matter what, always have since pool was finished in May 2012.
Mid jan, PB did another acid bath. This time I brought the ph up rather than letting him just dump a bunch of soda ash and leave. This time i premixed it in 2.5 lb intervals and slowly raised the ph up over a 2 day period, then added alkalinity up to get those levels up as well. Within a few days, same end result. Looks like white stains , plaster is very cloudy etc.
PB blames it on calcium in tap water. I had it checked, it was just 80 at the tap and 250 in the pool. Now he is saying the bi-product in the soda ash is what is attaching to the plaster. Plaster company came to take a look last week and did some spot treatments on the pool. Of course when they add in the acid the white substance instantly turns to milk and the perfect looking plaster is exposed. So he started trying to say "see, see, it look perfect with acid". I explained that i understood that and that i cannot swim in it when in the acid bath phase..... i told him the problem begins when we bring the ph back up. All the plaster company had to say is that they don't recommend salt systems with the plaster. ***?
So now, the PB did another acid bath on Tuesday. As of yesterday pool plaster looked great, but today it is beginning to turn white again....
Does anyone know how to cure this problem or have any input? I am about to lose my mind dealing with this pool.
