How to Keep Pool Water From Getting Hot

If you own a swimming pool, you've probably encountered a few heat waves that sent your pool water temperature soaring over 90 degrees Fahrenheit. Aboveground pools and any pool less than 6 feet deep are most susceptible to very warm water temperatures, as they heat up quicker than deeper pools and those built in the ground. By installing a simple device called an aerator to your swimming pool's return line, you keep your pool water cool even during the dog days of summer.

Instructions

- 1
  Turn off your swimming pool's filter and circulation system so no water flows into the pool. You don't want water running while you are installing the aerator.
- 2
  Locate one of the pool's water return lines. These are the holes or ports the water flows through after being cleaned by the filter system and emptying back into the pool. Look along the inside walls of your pool, and you should find a hole about halfway down the wall.
- 3
  Install the aerator plug into the return line port. Some aerator plugs will simply push into the return line, and you may not even need any tools. Make sure the aerator plug is firmly in place.
- 4
  Connect the aerator tube to the plug. The tube should be long enough so several inches of it sticks out of the water.
- 5
  Turn your water filtration and circulation system back on. The water running through the return line will now flow through the aerator. Water should mist out of the aerator into the air, then land back into the pool. Water traveling through the air is cooled by air molecules that cool the entire pool once it flows into the rest of the water. Adjust the aerator tube if the water is not landing back into the pool.
- 6
  Keep a cover on your pool during the day when not in use. This will prevent an abundance of sunlight from overheating the water.
