Hello everyone, I recently had a 22,000 saltwater pool/spa built. The builder owns a company that he swears is identical to Pebble Tec. He says it comes from the same quarry, same supplier and his installer told me he used to work for Pebble Tec. The installer also told me it is the exact same product. I wasn't told squat, nor did I know squat about the importance of balancing the water after first filling the pool. My builder got his last check and was MIA afterwards. After a couple of weeks I had my water tested PH was 8.0, TA was 180, CH was 150, CA was 0. The builder did pour some liquid chlorine (don't know amount or type) and the level was .5. Finally after two weeks of reading and reading my PH is 7.5, TA is 110, CH is 230, CA is 90 and Chlorine is 3.
My question regards the pebble plaster he put in. It looks bad and after finally tracking the builder down and getting him to come over, he is telling me this is completely normal. He calls it "fat". He says it's plaster that wasn't removed during the acid wash and will eventually come off. He says since it's saltwater it will take "a little longer", but assures me it will eventually look even and uniform. Some of the areas are just darker than others and it's easy to see that there is just more plaster that's hiding the pebble. These are very large streaks running the length of the pool. Other areas are "spots" that are not as dark, they look very light and look like something dripped and "splattered".
I've put some pics for the pros to look over and evaluate. I'm requesting him to rewash with acid. He says it shortens the life of the plaster and says just wait it out. Any thoughts/advice/recommendations are welcome and appreciated. Thanks
