A well-maintained pool can last for decades, providing endless enjoyment and adding value to your home. However, not all pools are the same, and the type of material your pool is constructed from—whether Gunite (concrete) or fiberglass—requires different care strategies to ensure it stays in top shape over the years. Proper maintenance is the key to maximizing pool longevity and avoiding costly repairs.
In this article, we’ll explore essential tips for taking care of both Gunite and fiberglass pools. Whether you’re a new pool owner or looking to refine your maintenance routine, these practices will help extend the life of your pool and keep it looking pristine for years to come.
- Understanding the Differences: Gunite vs. Fiberglass Pools
Before diving into specific maintenance strategies, it’s important to understand the fundamental differences between Gunite and fiberglass pool construction. Both types of pools have unique benefits, but their care requirements vary based on the materials used.
- Gunite Pools
Gunite pools are made from a mix of concrete and sand that is sprayed over a steel framework. This type of pool is highly durable and can be custom-shaped to fit any design, making it a popular choice for homeowners who want a long-lasting, customizable pool. However, because of the porous nature of concrete, Gunite pools require regular maintenance to prevent algae growth, surface stains, and cracks.
- Fiberglass Pools
Fiberglass pools are constructed from pre-molded fiberglass shells that are installed directly into the ground. These pools have a smooth, non-porous surface, which makes them resistant to algae and easier to maintain than Gunite pools. Fiberglass pools require less frequent cleaning and are less prone to surface damage, but they still benefit from routine maintenance to ensure longevity.
- Cleaning and Brushing: Keeping Your Pool Surfaces Clear
Proper cleaning is essential for both Gunite and fiberglass pools to prevent dirt buildup, algae growth, and staining. Regular cleaning helps maintain the appearance of the pool’s surfaces and extends their lifespan.
- Gunite Pool Cleaning
Because Gunite surfaces are porous, they are more susceptible to algae growth and staining. Regular brushing is critical to prevent algae from taking hold, especially on rough surfaces like plaster or pebble finishes. Use a pool brush with stiff bristles to scrub the walls and floor of the pool at least once a week, paying special attention to areas with less circulation, such as steps and corners.
Stains can also form on Gunite pools due to minerals in the water or organic materials like leaves. To prevent stains, remove debris from the water as soon as possible and check the pool’s water chemistry regularly.
- Fiberglass Pool Cleaning
Fiberglass pools are easier to clean due to their smooth, non-porous surface. Algae is less likely to grow, but it’s still important to brush the pool occasionally to remove any dirt or debris. Use a soft pool brush to clean the walls and floor without scratching the surface. Fiberglass pools also benefit from regular vacuuming to remove debris that settles on the bottom.
For both pool types, skimming the surface regularly and using a pool vacuum will keep the water clean and prevent debris from settling and staining the pool’s surfaces.
- Maintaining Water Chemistry: Balanced Water for Longevity
One of the most critical aspects of pool care is maintaining balanced water chemistry. Improper water balance can lead to a range of issues, from surface damage to corrosion of pool equipment. Regular testing and adjustments are necessary to protect your pool and ensure a safe swimming environment.
- pH and Alkalinity
Maintaining the correct pH and alkalinity levels is essential for both Gunite and fiberglass pools. If the pH is too low, the water becomes acidic and can corrode metal components, damage the pool surface, and cause irritation to swimmers. On the other hand, if the pH is too high, the water becomes basic, which can lead to scaling on the pool’s surface and equipment.
The ideal pH level for pool water is between 7.4 and 7.6. Alkalinity, which helps stabilize pH, should be maintained between 80 and 120 parts per million (ppm).
- Calcium Hardness
Gunite pools are particularly sensitive to calcium hardness, which refers to the amount of calcium dissolved in the water. If the calcium hardness is too low, the water will draw calcium from the concrete, leading to etching and surface damage. On the other hand, if the calcium level is too high, it can cause scaling and deposits on the pool surface and equipment.
For Gunite pools, maintain a calcium hardness level between 200 and 400 ppm to prevent surface deterioration. Fiberglass pools are less affected by calcium hardness, but it’s still important to keep the level in the proper range to prevent scaling and cloudy water.
- Sanitizer Levels
Proper sanitizer levels, such as chlorine or bromine, are crucial for keeping pool water clean and free from bacteria and algae. Regularly check the sanitizer levels and adjust as necessary to maintain a safe swimming environment. For both Gunite and fiberglass pools, chlorine levels should be kept between 1 and 3 ppm.
Using a pool testing kit or working with a professional pool service in Central Texas can ensure that your pool’s water chemistry is balanced, protecting both the pool surfaces and the swimmers.
- Preventing and Repairing Pool Surface Damage
Even with regular maintenance, both Gunite and fiberglass pools may develop surface issues over time. Identifying and addressing minor problems early can prevent more extensive damage and costly repairs down the road.
- Gunite Pool Surface Care
Over time, Gunite pools may develop cracks due to shifting ground, freeze-thaw cycles, or wear and tear. Small cracks can often be repaired with patching materials, but larger cracks may require professional attention. Regularly inspecting the pool’s surface for signs of cracking, discoloration, or rough spots can help you catch problems early.
Gunite pools also require periodic resurfacing to maintain the integrity of the pool. Depending on the material used (plaster, pebble, etc.), resurfacing may be needed every 10 to 15 years to keep the pool in good condition.

Fiberglass Pool Surface Care
Fiberglass pools are less prone to cracking than Gunite pools, but they can still suffer from surface damage, such as scratches or discoloration. Minor scratches can often be buffed out, while deeper scratches may require professional repair. To prevent surface damage, avoid using sharp objects or abrasive cleaning tools in the pool.
Fiberglass pools are also susceptible to staining, particularly if the water chemistry is not properly maintained. Regular cleaning and balancing the water chemistry can prevent most staining issues.
- Equipment Maintenance for Pool Longevity
Pool equipment, such as pumps, filters, and heaters, plays a vital role in maintaining water quality and circulation. Regular equipment maintenance is essential for both Gunite and fiberglass pools to ensure efficient operation and prevent premature equipment failure.
- Pool Pump and Filter Care
The pool pump is responsible for circulating water through the filtration system, ensuring that debris and contaminants are removed from the water. Regularly check the pump and filter for any signs of wear or malfunction. Clean or replace the filter as needed to maintain proper water flow and filtration.
- Heating Systems
If your pool is equipped with a pool heater, regular maintenance is necessary to ensure it operates efficiently. Check for any signs of rust, corrosion, or leaks in the heating system, and have it serviced by a professional if needed.
Regular maintenance of your pool’s equipment not only extends the life of the system but also ensures that your pool remains comfortable and safe for swimming year-round.
- Seasonal Maintenance Tips
Different seasons require different approaches to pool maintenance. Adjusting your care routine based on the time of year can help protect your pool from weather-related damage and ensure it’s ready for swimming season.
- Winterizing Your Pool
In colder climates, Gunite and fiberglass pools should be properly winterized to prevent freeze damage. This involves lowering the water level, draining the plumbing lines, and adding winter chemicals to prevent algae growth. Covering the pool with a durable pool cover also protects it from debris during the off-season.
- Opening for Summer
When preparing your pool for summer, perform a thorough inspection of the pool and equipment to ensure everything is in good condition. Clean and refill the pool, balance the water chemistry, and check that all systems are functioning properly.
