Best above ground pool installation pros near La Vale, MD

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.

Yes, you will need to shock your pool with high levels of chlorine or bromine when you first fill it to kill off bacteria and pathogens. You’ll need to wait for the chlorine concentration to come back down to a safe level before swimming. After that, you can test and maintain the chlorine and other levels as normal. The only exception to this is if you get pool water delivered by a professional. In that case, the water might come pretreated, so you might not need to shock it.

The generator in your saltwater pool conversion kit transforms sodium chloride—the same salt as table salt—into chlorine. A process called electrolysis sends electricity through the water to interact with the chlorine ion. This ultimately creates the chlorine that keeps your pool safe and clean. The cell in your saltwater chlorine generator is the part that converts the salt into chlorine.

Don’t worry if your pool is still cloudy right after shocking it. Some shocking products will leave your pool cloudy for a day or so after using them. However, if your pool is still cloudy several days after shocking it, it could be due to poor filtration, low chlorine, or one of the other problems outlined above. If you’ve tried our fixes but still can’t clear the cloudiness, call a pool repair professional.
