He everyone, I live in Texas- where a pool should be required.. We just constructed and filled our pool yesterday. We had "pool school" and were taught about chemicals and brushing the pool. I brushed the pool yesterday and went for my first dip. I noticed a black spot (small rock size) on the bottom step. Our pool in 3-6 feet, with 3 steps to enter.. When I touched it, it felt like an acorn and parts of it started peeling off like in layers. Now, there is a penny size "hole" where that foreign object was. I called the builder and they are going to look at it today. We chose a colored blue plaster and everywhere I have been reading says the undrwater plaster in white.. It is a 15000 gallon pool and really don't want to drain all that water. If it comes to that it there a way to reuse the water? Not to mention, I will have to find a way to redirect any water pumped out away from my neighbors, since I am on the top of a hill and the HOA will go crazy if that water kills the neighbors yards. Any suggestions, so I can be well prepped before the builder comes out today..
