Fiberglass Pool Maintenance 101

Keeping Your Pool Sparkling All Season Long

Owning a fiberglass pool is a fantastic way to bring endless fun and relaxation to your backyard oasis. Unlike other types of pools, fiberglass offers a smooth surface that inhibits algae growth, making maintenance simpler and less time-consuming. However, to ensure your pool stays in pristine condition and extends its lifespan, regular care is crucial. This comprehensive guide will cover essential maintenance tasks, from routine cleaning to water chemistry balancing and seasonal care.

Regular Cleaning Schedule

Skimming and Scrubbing

  • Daily: Use a skimmer to remove leaves and other debris from the water’s surface. This prevents staining and keeps your filtration system running smoothly.
  • Weekly: Gently scrub the walls and floor of your pool to prevent dirt buildup and algae formation. Fiberglass pools are durable, but use a soft brush to avoid scratching the surface.


  • Weekly: Vacuum the pool to remove debris and dirt that have settled on the bottom. Automatic pool vacuums can be a great investment for keeping your pool clean with minimal effort.

Filter Maintenance

  • Weekly to Monthly: Check and clean your pool’s filter according to the manufacturer’s instructions. A clean filter is essential for clear water and efficient pool operation.

Balancing Water Chemistry

Maintaining the correct chemical balance in your pool is vital for preventing algae growth and ensuring the water is safe for swimming.

  • pH Levels: Aim for a pH level between 7.2 and 7.6. Use a pH increaser or decreaser as needed.
  • Alkalinity: Maintain alkalinity levels between 80 and 120 ppm to help stabilize pH levels.
  • Sanitizer Levels: Chlorine or bromine levels should be kept within the range recommended by your pool manufacturer. This kills bacteria and other pathogens.
  • Shock Treatment: Perform a shock treatment every two weeks or after heavy pool usage to kill any lingering bacteria or algae spores.

Seasonal Care

Opening Your Pool

  • Spring: Inspect your pool for any damage. Clean the pool thoroughly, balance the water chemistry, and ensure all equipment is in good working order before opening your pool for the season.

Closing Your Pool

  • Fall: Lower the water level slightly, balance the chemicals, and clean the pool. Cover your pool with a quality pool cover to protect it from debris and weather conditions during the off-season.


In climates where freezing is a concern, take additional steps to protect your pool:

  • Drain water from the plumbing lines to prevent freezing and cracking.
  • Add antifreeze to the lines if recommended by your pool manufacturer.
  • Ensure the pool cover is secure and free of standing water or snow accumulation.

Regular Inspection

Periodically inspect your pool for any signs of wear or damage, such as cracks or discoloration. Early detection and repair of any issues can prevent more significant problems down the line.


Maintaining your fiberglass pool doesn’t have to be a daunting task. By following a regular cleaning schedule, keeping the water chemistry balanced, and performing seasonal care, you can ensure your pool remains a sparkling, inviting centerpiece of your backyard for many years. Enjoy the crystal-clear waters and the peace of mind that comes with a well-maintained pool. Happy swimming!
