Rectangular pools, particularly those made of vinyl or fiberglass, are the easiest to maintain. The long, straight sides, right angles, and smoother surface make regular cleaning a breeze without having to maneuver into curves and nooks. Rectangular pools also tend to be standard sizes, so you may have an easier time when it comes time to replace liners, covers, and other parts.

An aboveground pool should be level within 1 inch—and it starts to become unsafe after a couple of inches. Any slope will lead to an uneven distribution of water, which will put pressure on your pool’s structure, wearing down the pool liner. In certain cases, it could cause your pool to collapse. Even if you’re within a safe window, you may still notice that the water level is uneven.

How often you should add water to your pool depends on how quickly the water evaporates. Keep an eye on your skimmer box, if you have one. Top up the water in your pool if you notice the water levels are lower than the bottom third of your skimmer. This helps prevent damage to your pump. 

Replace all the water in your pool every five to seven years, depending on how often you use your pool, the weather, and whether or not you close your pool for the winter.

You should add chlorine within 48 hours of filling your pool with water. In just 24 hours, bacteria and algae will begin to grow and contaminate your water. After that point, you’ll need to shock the water with high levels of chlorine, and you’ll likely need to do additional vacuuming to get the pool clean. It’s important to check your chlorine levels two to three times a week and add more chlorine as needed to maintain a healthy level.
