Buying guide

What to look for

Verify Pool Diameter Accuracy

Before purchasing any 18-foot round solar blanket, physically measure your pool's diameter from the inside wall to the inside wall. Do not rely solely on the manufacturer's nominal size, as some pools may vary slightly due to installation. A cover that is too small will not provide adequate heat retention, while one that is too large may require trimming, which can void warranties or lead to fraying edges.

Understanding Material Thickness

Solar blankets are measured in mils, which indicates the thickness of the material. A 10-mil cover is lightweight and easy to handle but offers less insulation. A 16-mil cover is thicker, more durable, and provides superior heat retention but is heavier and more difficult to manage alone. Choose the thickness that aligns with your local climate, your physical ability to handle the cover, and your insulation goals.

Assessing Weight and Handling

Consider who will be responsible for putting the cover on and taking it off. Thicker, heavy-duty covers can be quite cumbersome for one person to manage without a reel system. If you do not have a reel, a lighter 10-mil or 12-mil cover might be more practical for daily use, even if it sacrifices a small amount of thermal efficiency compared to the 16-mil options.

Evaluating UV Resistance

Sunlight is the primary cause of degradation for solar blankets. Look for covers that explicitly mention UV-resistant materials in their product descriptions. High-quality UV inhibitors help the cover withstand prolonged exposure to the sun without becoming brittle or cracking. While all solar covers are designed to be in the sun, those with better UV protection will generally last longer and provide better value over multiple seasons.

Checking Compatibility with Reels

If you plan to use a solar cover reel, verify that the blanket material is compatible with standard reel attachment kits. Some heavier covers require more robust reel systems to prevent sagging or tearing at the attachment points. Always check the manufacturer's recommendations regarding reel usage to ensure that your setup will be secure and that the cover will roll up smoothly without bunching or getting caught.

Reviewing Warranty and Longevity

While many solar covers have similar designs, their expected lifespans can vary based on material quality and construction. Check the product listing for any mentioned warranty periods or expected durability claims. Keep in mind that real-world longevity depends heavily on proper maintenance, chemical handling, and storage practices. Treat any warranty as a baseline and focus on the quality of the materials described in the listing.

Considering Climate Specifics

Your regional climate should dictate your choice of cover. If you live in an area with very hot days and cold nights, a thicker 16-mil cover is usually the better investment to lock in the daytime heat. Conversely, if you live in a consistently warm region, a thinner 10-mil or 12-mil cover may be sufficient to manage evaporation and provide the modest heating boost you need.

Ownership guide

Setup, use, and maintenance

Regular Debris Removal

To prevent damage to the bubbles, use a soft broom or specialized pool cover pump to remove leaves, twigs, and stagnant water from the top surface before attempting to remove the blanket. Leaving heavy debris on the cover can cause it to tear or sink, which puts unnecessary stress on the material. Always ensure the surface is clear and dry whenever possible to extend the overall lifespan of the cover.

Chemical Balance Management

Always test your pool water chemistry regularly, as solar covers can trap chemicals like chlorine underneath the surface, potentially accelerating the degradation of the plastic. Follow the specific chemical concentration guidelines provided by your pool professional. If you shock the pool, keep the cover off until the chlorine levels return to the recommended range to prevent premature bleaching or brittleness of the material, which can lead to cracking.

Proper Folding and Storage

When not in use, avoid leaving the cover exposed to direct, intense sunlight while folded, as this can cause the material to overheat and warp. Use a reel system if available, or fold the cover loosely and store it in a cool, shaded area. Proper storage prevents the bubbles from collapsing and ensures that the material remains flexible and effective for the entire swimming season.

Cleaning the Surface

Periodically clean the cover using only mild soap and water if it becomes dirty or covered in algae. Avoid using harsh chemicals, solvents, or abrasive scrubbers, as these can easily damage the thin plastic layers and pop the insulating bubbles. Rinse the cover thoroughly with a garden hose and allow it to dry completely before storing it away to prevent mold or mildew growth during the off-season.

Seasonal Inspection Routine

At the start and end of every season, inspect the entire blanket for signs of thinning, cracking, or bubble loss. Check the edges for fraying, which often indicates that the cover has been exposed to too much sun or improper chemical levels. Early detection of damage allows for timely repairs or replacement, ensuring that your pool remains protected and energy-efficient throughout the summer months without unexpected failures during use.

FAQ

Pool Maintenance — FAQ

Do I need to trim my 18-foot solar cover to fit?

Most 18-foot round solar covers are designed to fit the pool dimensions exactly. However, if your pool has unique features or if the cover is slightly oversized, you may need to trim the edges. Use a sharp pair of heavy-duty scissors to cut the material carefully. Always check the manufacturer's guidelines first, as improper trimming can lead to fraying or may void any potential warranty coverage. It is best to measure twice and cut once, leaving a small gap around the perimeter to allow for proper water circulation and ease of removal.

How do I keep my solar cover from blowing away?

Solar covers are lightweight and can be easily displaced by strong winds. To keep yours secure, ensure it is properly tucked against the pool walls. If you live in a particularly windy area, consider using pool cover clips or a weighted system designed for solar blankets. Avoid using heavy objects that could damage the bubbles. If high winds are forecasted, it is often safer to remove the cover entirely and store it securely to prevent it from being damaged or causing potential safety hazards around your pool area.

Should the bubbles face up or down?

The bubbles on a solar pool cover should always face down toward the water. This design allows the air trapped inside the bubbles to act as an insulating layer, which is crucial for heat retention. Placing the bubbles facing down also helps the cover grip the water surface better, which reduces the likelihood of the cover blowing off in light winds. The smooth side should face up, as it is easier to clean and less prone to accumulating debris that could damage the bubble structure over time.

Will a solar cover stop algae growth?

While a solar cover helps by reducing evaporation and keeping debris out, it does not prevent algae growth on its own. In fact, because solar covers warm the water, they can sometimes create conditions where algae thrives if the water chemistry is not properly balanced. It is essential to maintain proper chlorine or sanitizer levels and monitor your pH regularly. The cover is a tool for heat and evaporation control, not a substitute for proper water chemistry management. Always follow your pool chemical manufacturer's instructions for maintaining a clean and safe swimming environment.

How long does a typical solar blanket last?

The lifespan of a solar blanket varies based on the thickness of the material, the intensity of the sun in your region, and how well you maintain it. Generally, a well-cared-for cover can last between two to four seasons. Factors that shorten its life include high chlorine levels, lack of proper storage, and leaving it exposed to direct sunlight when not in use. Regular cleaning and keeping the pool chemistry balanced are the best ways to maximize the longevity of your investment and ensure it continues to function effectively.

Can I use a solar cover with a pool heater?

Yes, using a solar cover in conjunction with a pool heater is highly recommended. The cover acts as an insulator, preventing the heat generated by your heater from escaping through the surface of the water. This significantly reduces the workload on your heater, which can save on energy costs and help the water reach your desired temperature much faster. It is a very efficient way to maintain a comfortable swimming temperature, especially during cooler nights or in regions where ambient temperatures fluctuate significantly throughout the day.

Is a 16-mil cover better than a 12-mil cover?

A 16-mil cover is generally considered more durable and offers better insulation than a 12-mil cover because the material is thicker. This makes it more effective at retaining heat, especially at night. However, it is also heavier and more difficult to handle manually. If you have a pool reel, the 16-mil cover is often the better choice. If you are handling the cover by hand, the 12-mil cover might be more practical. The 'better' choice depends on your specific needs regarding insulation performance versus the physical effort required for daily operation.

Can I leave my solar cover on during a storm?

It is generally recommended to remove your solar cover during a severe storm or high winds. Large, flat surfaces like solar blankets can act like sails, potentially causing damage to the cover itself or the pool structure if caught by strong gusts. Additionally, heavy rain and debris can overwhelm the cover, making it difficult to remove later. Taking the cover off and storing it in a safe, sheltered location is the best way to protect your equipment and ensure it remains in good condition for the rest of the season.

Final verdict

Bottom Line

Choosing the right 18-foot round solar blanket comes down to balancing your need for thermal efficiency with the physical realities of pool maintenance. Thicker 16-mil models offer superior heat retention for cooler climates, while 10-mil or 12-mil options provide a lighter, more manageable solution for daily use. Always prioritize proper chemical management and storage to ensure your cover lasts through the entire season.

Ultimately, an 18-foot solar cover is a practical investment for any pool owner looking to minimize evaporation and extend their swimming season. By selecting a cover that matches your pool's specific needs and committing to a routine of cleaning and careful storage, you can effectively manage your pool's temperature and reduce maintenance burdens.
