Q: Do you need to put sand under an above ground pool?

• <div><p>While you can install an above ground pool on most level surfaces, you&rsquo;ll need sand to protect your liner from tearing. For example, rocks, plants, and twigs can take a toll on your liner. Adding sand will help level the pool even more. For additional support, you can also use angled foam or a foam pool cove.</p></div>

Q: Is it okay to fill a pool overnight?

• <div><p>You should avoid filling your pool overnight&mdash;just as a precaution. You&rsquo;ll want someone around to check on the progress. If your hose springs a leak or you overfill your pool, you could end up with some costly water damage. At worst, you could flood your home&rsquo;s foundation. For this reason, ensure someone is home and awake, even if your pool takes a couple of days to fill.</p></div>

Q: What month should I open my pool?

• <div><p>In most cases, late May or early June are the most popular times to open a pool, depending on your location. It&rsquo;s a good idea to open your pool when the outdoor temperature sits consistently above 65 to 70 degrees (F). At this point, algae will begin to flourish in your water, so opening the pool and adding the proper chemicals will <a href="https://www.angi.com/articles/how-to-remove-algae-from-pool.htm">avoid excessive pool algae</a> growth.</p></div>
