Owning a fiberglass pool is a constant invitation to fun and relaxation, but proper care is essential to ensure long-term enjoyment. Fiberglass pools, known for their durability and low maintenance, still require specific care, whether you use traditional chlorine or a saltwater chlorination system (Salt System). Maintaining the right chemical balance and cleaning routine helps protect the pool’s surface and maximize the efficiency of filtration equipment.
If you want to extend the lifespan of your fiberglass pool and keep it in top condition for decades, follow these essential maintenance tips.
Why Do Fiberglass Pools Require Specific Care?
Fiberglass pools have an external gel coat layer that protects their surface from damage and stains. This layer reduces dirt and algae buildup, making maintenance easier than with concrete or vinyl pools. However, improper chemical balance, harsh cleaning practices, or environmental factors can affect this surface and the performance of essential equipment like pumps and filters.
Proper maintenance of chlorine-based or saltwater pools ensures chemical stability, prevents damage, and provides a safe swimming environment. Learn more about how pools add value to your home.
Key Maintenance Tips
Regularly Monitor Chemical Levels
Maintaining chemical balance is crucial for any fiberglass pool. Here are the ideal parameters:
- pH: 7.2 – 7.8
- Chlorine (Chlorine or Salt System): 1-3 ppm
- Alkalinity: 80-120 ppm (stabilizes pH)
- Calcium Hardness: 200-400 ppm (protects pool equipment)
- Salt (Salt System): 2700-3500 ppm (varies by generator brand)
An imbalanced pH can damage the gel coat or irritate swimmers’ skin and eyes. Excessive chlorine or salt can cause fading and damage filters and heaters.
Pro Tip: Use a digital water test kit or test strips weekly to monitor water quality.
Simplified Cleaning Routine
Even though fiberglass pools resist dirt buildup, regular cleaning preserves their pristine appearance:
- Use soft-bristle brushes to remove dirt from walls and the pool floor.
- Vacuum debris to prevent residue accumulation.
- Avoid abrasive or acidic products that could wear down the gel coat.
- For Salt Systems, be aware that salt may leave crystalline deposits. Use specialized cleaners to remove them safely.

Boost Cleaning with Shock Chlorination
Even if your fiberglass pool uses a Salt System, periodic shock chlorination helps remove contaminants.
When to use shock treatment?
- After heavy rain.
- When the water appears cloudy.
- After intensive pool usage.
For Salt Systems, monthly shock treatments eliminate persistent contaminants while keeping your pool water balanced.
Maintain Pool Equipment: Filters, Pumps & Chlorine Generators
The longevity of your fiberglass pool depends on properly maintained equipment:
- Filters: Clean or replace every six months.
- Pumps: Regularly check for blockages to prevent motor strain.
- Salt System Generators: Remove calcium deposits from generator plates every 3-6 months.
Pro Tip: Always consult the manufacturer’s guidelines for specific equipment maintenance instructions.
Reduce Evaporation and External Contaminants
- Use pool covers to keep out dust, leaves, and debris.
- In saltwater pools, covers reduce the need for frequent refilling and maintain stable salt levels.
Chlorine vs. Salt System: Key Differences
- Maintenance: Chlorine systems require manual chlorine addition, while salt systems automate chlorine production.
- Initial Cost: Chlorine systems have a lower upfront cost, whereas salt systems require a higher initial investment but save on chlorine costs over time.
- Chemical Action: Chlorine provides consistent sanitization but needs regular replenishment, while salt systems continuously generate chlorine from salt.
- Impact on Pool: Improper chlorine balance can cause surface damage, while excess salt may lead to residue buildup on equipment.
Although a Salt System doesn’t eliminate chlorine completely, it significantly reduces manual chlorine addition, providing a more consistent and swimmer-friendly experience.
Special Considerations for Salt Systems
- Avoid excessive salt levels, as high salt concentration can corrode equipment and leave white stains along the pool edges.
- Never drain your pool completely, as exposure to excessive heat and dust may damage the gel coat.
Make Your Fiberglass Pool Last for Years!
Whether you choose traditional chlorine or a Salt System, both require specific care to maintain your fiberglass pool in excellent condition. Regular chemical balance, proper cleaning, and routine equipment maintenance will ensure long-lasting enjoyment.
