Install Above Ground Pools questions, answered by experts

With a regular pool, the water is contained by visible walls that are higher than the water level. An infinity pool has one or more walls that are right at the waterline so they're not truly visible. For an invisible look, the lower wall is often made of glass or clear acrylic. The water laps over the lower edge and into a catch basin below where it gets pumped back into the pool.

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.

The total time to install an inground pool typically ranges from 8 weeks to 4 months. This timeline can be influenced by several factors, including permitting, site preparation, and the construction process itself.

Key phases and their typical durations include:

  • Permits: Obtaining necessary permits can take anywhere from two to six weeks.

  • Excavation and Site Preparation: This phase takes about a week but can be extended by problematic soil, unexpected ground conditions, or the need to move underground utility lines.

  • Construction: The actual build, including plumbing and electrical work, often takes one to two months. The pool material is a major factor here; a concrete pool needs about 30 days to cure, while installing a fiberglass or vinyl liner is much faster.

External factors can also cause significant delays:

  • Contractor Availability: Spring and summer are busy seasons, and high demand can lead to long waitlists, potentially adding months to your start date. It is often recommended to start planning and getting estimates up to a year in advance.

  • Other Delays: Weather, material shortages, complex designs, and other unforeseen challenges can extend the project timeline.

The best way to kill off an algae bloom in an aboveground pool is to shock it with a large dose of chlorine. Shock typically kills off algae in about one to three days, although it can take longer if the pool water is in poor condition. After the shock treatment, add algaecide to prevent algae from growing back, and test the water every few days with test strips to ensure the pool’s pH doesn’t get out of whack.

Pool chemical levels should include a pH between 7.4 and 7.6, alkalinity between 80 to 120 ppm, and chlorine from 1 to 3 ppm. The size and type of your pool determine additional chemical levels, such as stabilizers and pool shock, but you can get to know these numbers using our pool maintenance 101 guide.
