Install Above Ground Pools questions, answered by experts

Your aboveground pool might technically be able to stand without water, but you shouldn't consider it stable. Aboveground pools need the weight of water to provide adequate stability and prevent the walls from collapsing in. Be sure to fill your pool with water as soon as possible after installation.

The type of sand you need for your sand filter depends on the manufacturer’s instructions, but you’ll need to use sand specifically for pool filters. Silica sand is a wallet-friendly, common choice that’s relatively easy to replace. You’ll choose between various grades of sand and different-sized sand grains.

Generally speaking, you should expect to wait 24 to 48 hours after filling a pool before you use it. However, the actual timeline depends on a few factors. Most importantly, you need to shock the water with chlorine or an alternative to swimming pool chlorine and let the concentration come down to a safe level before using the pool. Additionally, most water sources will be cold, and it can take days before the sun or your pool heater warms your water to a comfortable temperature. Alternatively, getting water professionally delivered could have you swimming in just a few hours.

The number of gallons in your pool will determine how much chlorine you’ll need to add to your pool for the first time. Chlorine levels should fall between 1 and 3 ppm. It's crucial to read the instructions on your chlorine packet to determine the number of tablets to put in the water based on your pool's capacity.

Round and freeform pools are popular choices for a small backyard, although a small yard may be able to accommodate a variety of shapes. When planning a pool for your small yard, remember to take into account pool deck space, fencing requirements, and other pool-related factors that may limit your choices.
