Hi all! I recently bought a house with a pool. This is my first time owning a pool and I feel slightly overwhelmed. A few days ago we had to do a partial drain of the pool due to cyanuric acid levels being too high. After we drained it, I was able to get a better look at the surface of the pool. So I have a few questions: 1. What type of surface is this? 2. Why does the side of the pool like like this? 3. Should I be concerned about having to resurface the pool (I have no idea how old the pool is).
