Q: Can I use chlorine tablets in a salt water pool?

• <div><p>Yes, you can use chlorine tablets in a salt water pool. It is not the standard recommended practice, but if your pool needs more chlorine, adding tablets can help temporarily fix the problem. Only add as many tablets as needed to keep your chlorine level around three parts per million. After adding the tablets, test your water to determine the chlorine content.</p></div>

Q: How long does it take for a pool to heat up by the sun?

• <div><p>At noon, when the sun is at its highest point, sunlight can naturally increase the temperature of a pool by 0.7 degrees each hour, but this can depend on other external factors. For example, evaporation caused by the sun will cause a pool to lose up to 5 degrees for every 1/2 inch of water evaporated. Using a water heater will produce more reliable results.</p></div>

Q: Do pools ever go on sale?

• <div><p>If you wait until fall or winter, you might see sales on pools and pool materials, enabling you to save a good amount on this home improvement project. Sometimes pool servicing companies try to make space for next year&rsquo;s inventory, or the materials are cheaper when fewer construction projects happen during colder months. </p></div>

Q: Why am I losing water in my inground pool?

• <div><p>In-ground pools lose water naturally due to wind, heat, and humidity. They also lose water from the kiddos' cannonball competitions. But be mindful of the water level. If it drops too low and the pump draws in air instead of water, it will likely be damaged and require repair or replacement.</p></div>
