There are three types of pool filters—cartridge, sand, and D.E. (diatomaceous earth). Cartridge and sand filters are the most popular types and are affordable and easy to maintain. D.E. filters are more expensive and require more maintenance, but they are also very good at filtering out small particles.

Both above ground and inground pools can have pool liners. Inground pools made of gunite don’t need pool liners, and you’ve probably walked along an unlined pool and felt the ripples and ridges on the floors and walls. But adding a liner over gunite or other pool types helps protect the wall panels from algae growth.

It depends. Your pool might need chlorine every day if the water is exposed to direct sunlight and you use your pool frequently. UV light and constant use will deplete chlorine levels more rapidly. Test your water regularly to see where your levels sit and adjust accordingly. Generally speaking, most homeowners need to add chlorine following a water chemical test about one to three times per week.

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.
