Essential Chemicals

Here are some of the essential chemicals you should have on hand to maintain your fiberglass pool:

Liquid Pool Shock

Liquid pool shock is a powerful sanitizer that can quickly kill bacteria and other harmful organisms in your pool. Use it to shock your pool after heavy use or when the chlorine level drops too low.

pH and Alkalinity Increaser

Maintaining the proper pH and alkalinity levels in your pool is essential for keeping the water safe and comfortable to swim in. Use a pH and alkalinity increaser or decrease to adjust the levels as needed.


Stabilizer is an essential chemical for maintaining chlorine levels in your pool, especially in hot and sunny weather. It helps prevent the chlorine from breaking down too quickly, ensuring that your pool stays clean and clear.


Algaecide is a preventative chemical that helps keep algae from growing in your pool. Use it regularly to keep your pool looking beautiful and free from unsightly green or black growth.

Salt Water Pool Essentials

If you have a salt water pool, you'll need some additional items to keep it in top shape:


Be sure to keep at least 2-6 40-pound bags of salt on hand to maintain the proper salt level in your pool. The ideal salt level is between 2700-3400 ppm, with 3200 ppm being preferred. Use salt test strips to check the level regularly.

Maintenance Tips

In addition to having the right tools and chemicals, there are some essential maintenance tips you should follow to keep your fiberglass pool in top condition:

Brush the Water Line

Brushing the water line of your pool at least twice a week will help maintain a brilliant-looking finish and prevent buildup of dirt and debris.

Watch for Metal Objects

Be sure to keep metal objects, especially ones that can rust, away from the surface of your pool shell. This will prevent unsightly stains and discoloration from developing.

Avoid Bringing in Algae

Avoid using bathing suits that have been used in another body of water and haven't been washed, as this can bring types of algae into your pool.

Maintaining the Autocover

If you have an autocover for your pool, it's important to run it at least once a week. This will help keep the cover in good condition and prevent debris from accumulating on it. Additionally, it's a good idea to periodically check the motor box of the autocover to make sure it's free of debris. Blocked drains can cause problems with the cover and may even damage it.

Testing the Pool Water

To keep your pool water healthy and clean, it's important to test it regularly. You can use a test strip or take a sample of water to a nearby pool store for analysis. It's recommended to test your pool water at least once a week. Maintaining proper pH and chlorine levels can help prevent algae growth and other issues with your pool.

Maintaining Pool Equipment

In addition to maintaining the pool water, it's important to take care of your pool equipment. This includes checking and emptying the skimmer and pump strainer basket often to prevent debris from clogging the system. If your pool has a sand filter, it should be backwashed at least once a week to remove accumulated debris. Keeping the water level in the middle or 1 inch from the top of the skimmer can also help keep the system running smoothly.

By following these maintenance tips and keeping the necessary items and chemicals on hand, you can keep your fiberglass swimming pool in top condition for years to come.
