Inground fiberglass pools are a popular choice among homeowners due to their durability, low maintenance, and aesthetic appeal. However, even though they require less maintenance than other types of pools, they still need regular upkeep to keep them in top condition. In this article, we will discuss some tips and tricks for maintaining your inground fiberglass pool.

Keep the Water Clean:

One of the most important aspects of maintaining a pool is to keep the water clean. You should test the water regularly to ensure that the pH, alkalinity, and chlorine levels are within the recommended range. You can use a testing kit or take a sample of water to your local pool store for testing during and after fiberglass pool installation.

It is also important to skim the surface of the water regularly to remove debris such as leaves, bugs, and other floating objects. You should also vacuum the bottom of the pool to remove any dirt or debris that has settled there.

Maintain the Filter:

The filter is an essential component of your pool’s circulation system. It helps to remove dirt, debris, and other contaminants from the water. You should clean or replace the filter regularly to ensure that it is functioning properly.

If you have a sand filter, you should backwash it every few weeks to remove any trapped debris. If you have a cartridge filter, you should remove and clean it every few months. If you have a DE filter, you should backwash it and add new DE powder every few months.

Check the Pump:

The pump is the heart of your pool’s circulation system. It circulates the water through the filter and back into the pool. You should check the pump regularly to ensure that it is working properly. If you notice any strange noises or a decrease in water flow, you should have it inspected by a professional.

Clean the Pool Surface:

In addition to skimming the surface of the water, you should also clean the pool surface regularly. Fiberglass pools are prone to staining, so you should brush the walls and floor of the pool regularly to prevent any buildup of algae or other contaminants.

You should also check the waterline of the pool and clean any buildup of dirt or oils with a tile cleaner or a mixture of baking soda and water. Avoid using abrasive cleaners or tools that could damage the surface of the pool.

Maintain the Water Level:

The water level of your pool can affect the overall health of the pool. If the water level is too low, the pump can become damaged or the pool could become unbalanced. If the water level is too high, it can put strain on the pump and filtration system.

You should check the water level regularly and add water as needed. If you notice that the water level is dropping quickly, it could indicate a leak in the pool, and you should have it inspected by a professional.

Winterize the Pool:

If you live in an area with cold winters, you will need to winterize your pool to prevent damage from freezing temperatures. You should drain the water from the pool and the filtration system, and add antifreeze to prevent any remaining water from freezing and damaging the pipes.

You should also cover the pool with a winter cover to keep out debris and prevent any damage from snow or ice buildup.

Hire a Professional:

Maintaining a fiberglass inground pool can be a lot of work, and sometimes it’s best to leave it to the professionals. A pool service company can provide regular maintenance, such as cleaning, chemical balancing, and filter replacement.

They can also inspect your pool for any damage or leaks and make repairs as needed. Hiring a professional can save you time and ensure that your pool is always in top condition.


In conclusion, maintaining an inground fiberglass pool requires regular upkeep, but it is worth the effort to keep your pool looking great and functioning properly. By following these tips and tricks, you can ensure that your pool remains a refreshing and enjoyable place to relax and entertain.

Remember to keep the water clean, maintain the filter and pump, clean the pool surface, maintain the water level, and winterize the pool if necessary. If you feel overwhelmed or simply don’t have the time to devote to pool maintenance, consider hiring a professional to take care of it for you.

By taking care of your inground fiberglass pool, you can extend its lifespan and keep it looking beautiful for years to come. With a little bit of effort and attention, your pool can be a source of relaxation and enjoyment for you and your family.
