Filter balls don’t work as well as sand filters because they’re unable to handle large debris, are prone to clogging, and require frequent cleaning. While they can seem more convenient and less expensive than sand filters, most need to be removed and washed regularly, or they won’t filter well and struggle with algae and dirt. Speak with your pool maintenance pro about the best filtration option for your pool.

Unless you have an alternative to chlorine in your pool to prevent bacteria and viruses from taking up residence in your water, it’s not safe to swim in a pool without enough chlorine. According to the Centers for Disease Control and Prevention (CDC), swimming in a pool with insufficient chlorine could lead to skin and eye irritation, ear issues, respiratory distress, such as coughing and congestion, and various other health issues. Always make sure your chlorine levels are healthy and stable before swimming for proper pool safety.

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.

Aboveground pools take between one day to a few days to install, depending on the pool size and type. Your project may take longer if you’re planning to complete other projects simultaneously, like building a deck around the pool. If your land is hilly or rocky, you’ll also need to budget time for the land preparation. Aboveground pools need to be installed on a level surface.
