We finished our pool about 2 weeks ago. We used Hauk Custom Pools and I am in the Frisco, TX area. I love our design, and landscaping, and the decking, and it is just how I envisioned it! However... I am not happy with our plaster, and evidently several other people are not as well, as today they sent out an email saying they have lots of plaster complaints about staining and spots so they are coming out to review all the latest builds. Everything was smooth up until plaster. Our pool is 34X18.5 rectangular, and the spa is 8X8. We used Hauk's pebble, which is Sea Blue. I had them use larger rebar on the pool beam and we also did chemical soil injection. We always had water in the bottom of our pool. Even after they dug it, it was wet at the deep end, which is 6 feet deep. Water was always in the bottom deep end after gunite. I pumped it daily. Even at plaster, there was water there, but multiple people from Hauk, the plaster company, our Project Manager, all said, nothign to worry about, plaster actually cures underwater. I figured these guys know what they are going, and the plaster guy is not going to want to have to redo a job, so I left it to the experts. The rain delayed us a bit, but we got plaster, I filled it up, brushed it 3 times a day. Pool school was kind of a joke, the guy showed me how to run everything and basically told me to keep chlorine tabs in the holder and check the PH. I bought a test kit and I test my water every day, because I know how important it is in the beginning. I have been reading tons of articles online and educating myself. After we filled the pool, I noticed several darker areas. They assured me they would clear up if I brushed it. I am a new pool owner, I have never owned a pool before, so I trusted them. Now brown spots are starting to show on the plaster, along with white areas. My PH is been 7.4 to 7.6 consistently. I did add some calcium hardner to bring the calcium up to 200. I took my water to Leslie Pools to have them test it weekly as a backup as well. Tony at the Frisco store has been amazing, and has yet to sell me anything, he has just tested the water, and gave me advice. I put a Vitamin C on the brown spots, and they cleared up. Hauk is coming out tomorrow to look at our plaster. The guy at Leslie's, told me nothing with my water has caused any plaster problems, because my water is perfect. I attached some photos. Does this just look like a bad plaster job? Again, never owned a pool so I have no idea!!
