Install Above Ground Pools FAQs, answered by experts

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.

Liquid chlorine is better for shock treatments or instances where you need to raise your chlorine levels quickly. Tablets are better for regular maintenance. Tablets take more time to dissolve but require less effort. You don’t need to measure out volume, and you can set them in a floater and let that do the work.

Setting up a pool on unlevel ground is not recommended as it can damage the pool or yard and put the safety of those using it at risk. If a pool isn't level, the water's weight won't distribute evenly, putting excessive pressure on certain parts. This can cause the pool liner to tear or the walls to collapse, leading to water damage, expensive repairs, or potential injury to swimmers. It is more cost-effective to level the ground correctly before installation rather than waiting to address serious structural issues later.

While you shouldn’t notice water that has an appropriate amount of chlorine in it (less than 4 parts per million), you could feel sick from drinking overly chlorinated water. Chlorine exposure can cause nausea, vomiting, coughing, and dizziness. Chronic chlorine exposure (meaning multiple or repeated instances) can make you feel like you have the flu, according to the CDC.

You can turn your aboveground chlorinated pool into a saltwater pool. The cost of a saltwater pool conversion is between $750 and $2,000, depending on your pool’s size. A saltwater pool offers benefits like less maintenance and water that is gentler on your skin. You’ll need to replace the salt every five years, but you won’t need to clean your pool as frequently.
