when completing your pool project, make sure you get a cleaner installed so it picks up all the debris from the floor and there's no stainings left by any debris. Also, make sure to keep the chemistry properly. Right? If you have a high pH, you can have calcium buildup or etching on the pool plaster. Make sure your pH is in balance. Also, make sure you check your pool equipment once a month to make sure that it's working in order. There's no leakage, there's no problem, and everything is working properly.
