Fibreglass Pool Maintenance: Crystal Clarity & Longevity

Are you looking for a backyard oasis that’s both aesthetically pleasing and a place to unwind?

A fibreglass pool might just be the ideal solution. But, as any seasoned pool professional will tell you, the beauty and longevity of a fibreglass pool lies in its upkeep.

If you’re considering the addition of a fibreglass pool to your home, we can guide you through the basics of fibreglass pool maintenance tailored to keep your pool in pristine condition.

Let’s get started.

Basic Fibreglass Pool Maintenance

Pool Cleaning and Skimming

Begin your pool cleaning routine with the simplest step: skimming. Using a long-handled net, gently glide over the water’s surface to capture leaves, insects, and other floating debris. This daily habit prevents clogs in your filtration system and keeps the water looking fresh

Next, equip yourself with a soft-bristled brush designed for fibreglass surfaces. Weekly brushing of the walls and floor dislodge algae and dirt before they become problematic.

Balancing Chemicals

Regularly test the pH level, aiming to maintain it between 7.2 and 7.8. This balance ensures the water chemistry is neither too acidic, damaging the pool surface and equipment, nor too alkaline, which can cause scaling and cloudiness.

Alongside pH, keep a close eye on chlorine levels (2-4 ppm), alkalinity (80-120 ppm), and calcium hardness (200-400 ppm) to foster a harmonious water environment.

Filter Maintenance

Clean the filter basket weekly and backwash the filtration system as the manufacturer recommends. This prevents debris build-up, ensuring efficient water filtration and reducing the strain on your pool pump.

Water Level and Circulation

A consistent water level is crucial for maintaining the efficiency of your skimmer and filter system. Too low, and your pump risks running dry; too high, and your skimmer’s effectiveness wanes. Aim to keep the water level midway up the skimmer opening for optimal performance.

Additionally, regular circulation is key. Running your pool’s pump for about 8-12 hours a day during the swimming season promotes even chemical distribution and prevents stagnation.

Seasonal Maintenance Tips for Your Fibreglass Pool

With each season comes a unique set of considerations to keep your fibreglass pool in top condition. Tailoring your maintenance approach to the time of year can help you manage your pool more effectively.

Spring: Awakening Your Pool

  • Wake-Up Call: If you’ve winterised your pool, spring is the time for a thorough inspection. Check for any damages or wear that may have occurred during the winter months. Ensure all equipment is functioning correctly before you start regular use.
  • Water Chemistry: Balancing your pool’s chemistry after refilling or topping up the water. This includes adjusting pH levels, alkalinity, and chlorine levels to within their ideal ranges. A shock treatment may be necessary to address any lingering bacteria or algae.
  • Cleaning: Give your pool a comprehensive clean. Brush the walls and floor, vacuum the pool, and clean out the filter system to remove any accumulated debris over the winter.

Summer: Peak Season Care

  • Daily Duties: Skimming debris from your pool daily and checking the water level becomes even more crucial during the hot months when the pool sees more activity.
  • Weekly Water Testing: With increased use, monitoring your pool’s chemical balance weekly helps prevent algae growth and ensures the water remains safe for swimming.
  • Filter Maintenance: Summer demands more from your filtration system, so clean your filter regularly to maintain optimal water clarity and hygiene.

Autumn: Preparing for Cooler Times

  • Debris Management: Falling leaves can become a significant issue. Continue skimming your pool regularly, and consider using a pool cover to minimise debris.
  • Reduced Filtration Time: As the temperature drops and pool usage decreases, you can reduce the filtration time accordingly. However, maintain water treatment to prevent algae and bacteria buildup.
  • Balance Water Chemistry: Before the cold fully sets in, ensure your pool’s chemical levels are balanced to avoid complications when winter arrives.

Winter: Protecting Your Pool

  • Winterising: In colder climates, winterising your pool can protect it from freezing damage. This includes lowering the water level, draining equipment, and possibly adding antifreeze to the pipes.
  • Pool Cover: A quality pool cover is indispensable for keeping out debris and maintaining water quality throughout the winter.
  • Occasional Checks: Even if your pool isn’t in use, periodic checks on the water level, pool cover integrity, and a glance at the pool equipment can prevent surprises come spring.

Advanced Maintenance Tips for Fibreglass Pools

1. Stain Prevention and Removal

Even with diligent maintenance, fibreglass pools can develop stains from minerals, algae, or organic material. Identifying the type of stain is the first step towards effective removal. For organic stains, shock treatments and brushing can be effective. For mineral stains, specially formulated removers may be necessary. Regularly using a pool clarifier can help prevent stains by coagulating tiny particles into larger, filterable sizes, keeping your pool water sparkling.

2. Annual Professional Inspection

While fibreglass pools are known for their durability, an annual check-up by a pool professional can help identify potential issues before they become major problems. This can include checking the structure for any signs of wear, inspecting the equipment for efficiency, and ensuring all safety features are in working order.

3. Efficient Use of Pool Covers

A pool cover keeps debris out and reduces evaporation, saving water and chemicals. During hotter months, a solar cover can help warm your pool using the sun’s energy, reducing heating costs. In cooler seasons, a safety cover can protect your pool from the elements and provide an added layer of safety when the pool is not in use.

4. Update Pool Equipment

Technology in pool equipment is continually advancing, offering more energy-efficient pumps, robotic cleaners, and smart systems that can automate much of the maintenance process. Upgrading to a variable-speed pump can reduce energy use, while automatic pH and chlorine dispensers balance the water chemistry without constant monitoring.

5. Eco-Friendly Practices

Incorporating eco-friendly practices into your pool maintenance can save money and reduce environmental impact. Consider installing a rainwater collection system to top off your pool, reducing your reliance on council water. Solar panels can power your pool equipment, and choosing natural pool chemicals can minimise the ecological footprint of your pool.


A fibreglass pool requires maintenance that blends ease with essential care, ensuring it remains enjoyable and beautiful through all seasons. Skimming and cleaning your pool regularly, balancing the water chemistry and making seasonal adjustments all contribute to its enduring beauty.
