How long after pool opening can you swim?

• <div><p>It’s a good idea to wait at least 24 hours after opening your pool before you swim in it. Pool opening often involves shocking the water, and the chemical levels need to come down a bit before it’s safe to swim. You can continue testing your water pH and chlorine levels if you’re in a rush. It’s wise to wait until your chlorine levels drop to under four parts per million (ppm) and you have a water pH of between 7.2 and 7.8. You can artificially <a href="https://www.angi.com/articles/how-to-lower-pool.htm">lower your water pH</a> to speed up the process.</p></div>

How long does it take for pH to lower in a pool?

• <div><p>Once you use a pH decreaser, you can expect the pH to adjust in two to four hours. If you use a strong chemical like muriatic acid, it could take as little as an hour. Either way, it’s best to wait for a full turnover cycle before retesting. You want to make sure the chemical is completely dissolved and evenly distributed or you won’t have a stable pH level.</p></div>

Q: Does pool water damage artificial grass?

• <div><p>Pool water&mdash;or rather, the chlorine in pool water&mdash;generally doesn&rsquo;t damage artificial grass. This type of grass is made from plastic fibers that are incredibly resilient. That said, you can damage artificial grass around a pool in other ways. For example, the sun&rsquo;s reflection off a window or fence can melt polyethylene fibers. A temporary pool can flatten and cause an indent in turf.</p></div>

Q: Do I need permits for an inground pool?

• <div><p>Yes, you will need <a href="https://www.angi.com/articles/how-much-does-building-permit-cost.htm">building permits</a> for an inground pool, and your pool installation company should pull them for you. The permit filing fee will usually sit between <b>$400 and $1,800</b>, and it should appear on your contract or invoice. You may want to confirm with your contractor that they will pull all necessary permits. You might also need a permit for a new fence, as many municipalities have special fencing requirements for properties with pools. A fence permit costs between <b>$50 and $500</b>. This expense may not be included in your pool installation estimate.</p></div>

Q: How long does it take for a pool heater to heat a pool?

• <div><p>The time it takes for a pool heater to heat a pool can range from eight to 48 hours, with an average of about 12 hours for the initial heating. For a more specific example, an average-sized 15,000-gallon pool may take six to 10 hours to heat up by 10 degrees. The exact duration depends on several factors, including the pool's size, the type and size of the heater, the starting water temperature, and the outside air temperature. It may take some trial and error to determine the precise time your specific pool takes to reach a desired temperature.</p></div>
