How long can water sit in a pool without chlorine?

• <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>

Q: How do you find a good inground pool company?

• <div><p>Finding a reputable inground pool installation company starts with an online search and assessing a company&rsquo;s positive and negative reviews. You can also check the Better Business Bureau&rsquo;s reports for companies you&rsquo;re considering to see if they have numerous customer complaints for poor service. One of the best things you can do to find a good company is ask for references and then call those past customers to see how they felt during the installation process and how their pool has held up. Finally, you can get estimates from the remaining companies to compare.</p></div>

Q: Are gunite pools hard to maintain?

• <div><p>Gunite pools are not exactly easy to maintain&mdash;but we wouldn't call them &quot;high maintenance.&quot; It's one of the longest-lasting pool options, but its porous surface does require a lot of care. You&rsquo;ll need to thoroughly clean the pool often to prevent stubborn algae growth, and the pool will require higher chemical levels to keep it clean. </p></div>

Q: Can I drain my aboveground pool into my yard?

• <div><p>It's not a good idea to drain an aboveground pool into your yard since the pool water's chemicals can harm your plants and the surrounding ecosystem. Instead, it's best to drain the pool into an appropriate sewer so it can be processed at a water treatment plant. You might also be able to drain it into your storm drain, depending on your region. Check with your city to learn about any relevant regulations.</p></div>

Q: What is the least expensive time of year to build a pool?

• <div><p>Off-season pool-building prices often align with the time of year you're least likely to use a pool. Many contractors offer deals in the late fall and winter to bolster the slow time of year. However, if you live in an area with freezing winters, you'll need to wait beyond the final frost and threats of extreme weather.</p></div>
