New Pool in TX

Hi, My name is Douglas, grew up in FLA with a pool, but I was just slave labor for my parents to vacuum the pool. They tricked me into thinking that was a 'treat'. haha Anyway, 45 years ladder and contractors are just finishing up on our fiberglass pool. Of course, they insisted it was level, but once it was full of water, the truth came out. Looks like we are going to attempt to hide their issue with waterline tile. Gosh I hope that works. So ******. Anyway, new to chemicals and all that stuff, so taking a 'plunge' into a new area to learn. Thank you
