• <div><p>You should add chlorine within 48 hours of <a href="https://www.angi.com/articles/cost-fill-pool-water.htm">filling your pool with water</a>. 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.</p></div>

What should I put down before installing an above ground pool?

• <div><p>Sometimes, homeowners choose to install their pool on concrete, foam tiles, or patio pavers. Leveled dirt is also fine, as long as it’s not sod or grass. Regardless, you’ll need to install sand as a buffer to prevent your liner from tearing. Some pool installers also use a protective foam pool pad.</p></div>

Q: Can you replace a pool light underwater?

• <div><p>It&rsquo;s fair to be concerned about handling pool lights or wiring in a pool filled with water. But fortunately, pool lights and swimming pools are designed to make it easy and safe to replace the lights without needing to drain the water. Instead, you can turn off the electricity to the pool as a safety precaution, unscrew the pool fixture, pull it up and out to the side of the pool, then change the bulb.</p></div>

Q: How quickly will a solar cover heat a pool?

• <div><p>A solar cover can heat your pool anywhere from 5 to 15 degrees Fahrenheit over the course of 6 to 12 hours, depending on how much full sun your pool gets and how big it is. When used in conjunction with a solar pool heater, your pool will heat up even faster, all while using less energy than a traditional pool heater. </p></div>
