Q: What types of pool filters are there?

• <div><p>There are three types of pool filters&mdash;cartridge, sand, and D.E. (diatomaceous earth). Cartridge and sand filters are the most popular types and are affordable and easy to maintain. D.E. filters are more expensive and require more maintenance, but they are also very good at filtering out small particles. </p></div>

Q: How long does it take to cool a pool with a chiller?

• <div><p>A pool chiller will take anywhere from 12 to 14 hours to lower your pool's temperature by 1 to 15 degrees. Most people tend to run their coolers overnight, but larger pools in warm climates take longer to cool. Choosing a chiller with the right capacity can help speed up the process.</p></div>

Q: Is it better to use liquid chlorine or tablets in a pool?

• <div><p>Liquid chlorine is better for shock treatments or instances where you need to raise your chlorine levels quickly. Tablets are better for regular maintenance. Tablets take more time to dissolve but require less effort. You don&rsquo;t need to measure out volume, and you can set them in a floater and let that do the work.</p></div>

Q: Is it worth converting to a saltwater pool?

• <div><p><a href="https://www.angi.com/articles/pool-remodel-cost.htm">Pool remodel costs</a> average over $9,000, so what about converting your pool to salt water instead? It is certainly an investment on the front end, but homeowners stand to save money on maintenance by switching to a saltwater pool. You will need to replace the salt cell every five years or so, but you will not have to clean your pool as frequently, either. The smell of chlorine also will not be on your swimsuits or skin, which is a benefit many appreciate.</p></div>

Q: Can I install a pool myself?

• <div><p>It is possible to <a href="https://www.angi.com/articles/install-above-ground-pool.htm">install an above-ground pool yourself</a> in about six hours, provided your yard isn't too sloped or you don't have many trees. It's imperative to ensure your ground is level; otherwise, your pool could collapse. Contact a swimming pool installer for an in-ground pool installation or to ensure your above-ground pool is installed correctly.</p></div>

"Excellent! Kirk, the General Manager was also the sales person. He was helpful, honest, forthright, personable, prompt, dependable, and reachable. His crew were professional and hard working. Their craftsmanship was excellent. They got my house and garage roof done in one day! As well as installed the gutter guards. They were near the cheapest bid but were not the cheapest but, I hired him/them because he had all the positive qualities listed above. I would recommend them, as well as hire them again!"
