Q: How often do you need to change the water in an aboveground pool?

• <div><p>Completely refreshing the water in an aboveground pool every five to seven years helps keep it free of bacteria and algae. Emptying the pool also allows you to clean, repair, or replace the pool liner. Schedule your water change when the weather is mild, as intense heat or cold can damage the pool liner when the pool is empty.</p></div>

Q: Are shock and chlorine the same thing?

• <div><p>No, shock and chlorine are not the same thing, though they are related and both are used for pool maintenance. Regular chlorine, often in the form of tablets, is a sanitizer used for routine, day-to-day maintenance to keep a steady chlorine level. Pool shock, however, is a highly concentrated dose of chlorine used periodically for a more intense cleaning. It rapidly raises chlorine levels to fix issues like cloudy water or algae growth and also eliminates chloramines, which are byproducts of regular chlorination. Because their purposes and concentrations differ, they are not interchangeable, and proper pool care typically requires using both.</p></div>

Q: How much does a pool booster pump cost?

• <div><p>A <a href="https://www.angi.com/articles/pool-pump-cost.htm">pool booster pump costs</a> between $700 and $4,000 on average. The type and size of pump are the biggest factors that influence the cost. The average price of labor will also play a role since you should hire a pro to install a pool booster pump for you. </p></div>
