Buying guide

What to look for

Assessing Material Thickness

Solar covers are measured in mils, with higher numbers indicating thicker material. A 10-mil cover is lightweight and budget-friendly, while 12-mil or 16-mil options offer better insulation and durability. Consider your local climate and how often you handle the cover; thicker blankets provide superior heat retention but are heavier to remove and store. Choose the thickness that balances your need for thermal performance with your physical ability to manage the cover daily.

Verifying Pool Dimensions

While these covers are labeled for 18-foot round pools, always measure your pool diameter from the inside edge of the wall to ensure a proper fit. Some pools may have unique coping or structural features that require a slightly larger or smaller diameter. Verify if the manufacturer provides trimming instructions, as some covers are designed to be cut to size if the fit is slightly oversized for your specific pool configuration.

Evaluating Bubble Design

The bubbles on a solar cover are the primary mechanism for heat absorption and retention. Look for designs that maximize surface contact with the water. While most standard covers use a similar bubble structure, some higher-end models may claim better heat transfer efficiency. Read user feedback to see if others report consistent heating results, but remember that actual performance depends heavily on your local sunlight exposure and ambient air temperatures throughout the season.

Checking Compatibility Requirements

Before purchasing, verify if the cover is intended for above-ground or in-ground use, or if it is versatile enough for both. Above-ground pools may require different anchoring or trimming compared to in-ground pools with deck-level edges. Check the product specifications to ensure the material is compatible with your pool type, especially if you have specific features like ladders, skimmers, or return jets that might interfere with a standard round cover layout.

Considering Ease of Handling

A solar blanket must be removed to swim, so consider how you will manage it. A 16-mil cover is significantly heavier and more cumbersome than a 10-mil version. If you are a solo user or have limited physical strength, you might find a lighter cover easier to manage, or you may want to budget for a solar cover reel system to assist with rolling and storing the blanket daily.

Reviewing Material Durability

Look for descriptions highlighting UV-resistant PE materials. Since the cover will be exposed to intense sunlight for long periods, UV protection is crucial to prevent the plastic from becoming brittle. While all solar covers eventually degrade, those explicitly marketed as heavy-duty or UV-stabilized generally offer a longer service life. Compare the provided material descriptions to understand the expected lifespan and durability before making your final selection for your backyard pool.

Understanding Warranty Limitations

Always check for manufacturer warranty details regarding material defects or premature degradation. Since solar covers are consumable items, warranties are often limited in scope and duration. Understand what is covered—such as seam failures or manufacturing defects—versus what is considered normal wear and tear from sun and chemical exposure. This knowledge helps manage expectations regarding the product's lifespan and the potential need for future replacements after several seasons of consistent use.

Ownership guide

Setup, use, and maintenance

Regular Debris Removal

To prevent organic matter from decaying on your solar blanket, use a soft pool brush or a dedicated leaf net to clear the surface regularly. Accumulation of leaves and twigs can lead to staining and premature material degradation. Always ensure the cover is clear before removing it from the pool to prevent debris from falling into your water, which would otherwise increase the workload on your filtration system and necessitate additional chemical treatments.

Proper Chemical Balancing

Solar covers trap chemicals beneath them, which can potentially accelerate the degradation of the pool liner or the blanket itself if levels are not monitored. Consult your pool chemical manufacturer’s guidelines to ensure your sanitizer and pH levels are within the recommended range. Avoid using excessive shock treatments while the cover is deployed, as high chlorine concentrations can bleach and weaken the PE material, significantly shortening the lifespan of your solar blanket.

Gentle Cleaning Techniques

When the cover becomes soiled, use only mild, non-abrasive soap and a soft sponge to clean the surface. Rinse it thoroughly with a garden hose to remove any residue. Never use harsh chemicals, solvents, or pressure washers, as these can damage the bubble structure or puncture the thin material. Regular, gentle rinsing helps maintain the clarity of the material, which is essential for effective solar heat absorption and overall longevity.

Seasonal Storage Protocols

During the off-season, your solar blanket must be thoroughly cleaned, dried, and stored in a cool, shaded area. Fold or roll the cover carefully to avoid creasing the bubbles. Exposure to direct sunlight while the cover is off the pool can cause the material to become brittle and crack. A protective cover or storage bag is recommended to keep pests and environmental elements away from the material during long storage periods.

Periodic Material Inspection

Frequently inspect your solar blanket for signs of wear, such as thinning, bubble popping, or fraying edges. Small tears can often be repaired with specialized pool cover tape, but significant degradation indicates the material has reached the end of its functional life. Early detection of wear helps you plan for a replacement before the cover loses its ability to retain heat or prevent water evaporation, keeping your pool maintenance routine predictable.

FAQ

Pool Maintenance — FAQ

How do I know if this cover will fit my pool?

Always measure your pool diameter from the inside edge of the wall. If your pool is exactly 18 feet, an 18-foot cover should fit, but some models are designed to be trimmed. Check the product listing to see if the manufacturer specifies that the cover is trimmable. If your pool has an irregular shape or unique features like a built-in ladder, ensure the cover material can be safely cut without compromising its structural integrity or warranty status. When in doubt, consult your pool manufacturer's guidelines for recommended cover sizes and fitting procedures.

Will a thicker cover heat my pool faster?

A thicker cover, such as a 16-mil model, is primarily designed for better heat retention and durability rather than faster initial heating. While it provides a superior thermal barrier to prevent heat loss, the actual rate of heat absorption depends largely on the amount of sunlight the cover receives and the surface area exposed. Thicker covers are generally more effective at keeping the water warm overnight, which can lead to a higher cumulative temperature over time, but they do not necessarily increase the speed of the heating process itself compared to thinner options.

Can I use this cover on an in-ground pool?

Some solar covers are designed specifically for above-ground pools, while others are versatile enough for in-ground use. Always check the product description to confirm compatibility. In-ground pools often have different coping and deck configurations that may affect how the cover lays and how it is secured. If a product listing does not explicitly state it is suitable for in-ground pools, it is safer to look for a model that specifically mentions in-ground compatibility to ensure a proper fit and safe operation during the swimming season.

How do I prevent the cover from blowing away?

Solar covers are lightweight and can be displaced by strong winds. While most covers are held in place by the water surface tension, they do not typically include physical anchoring systems. If you live in a windy area, you may need to consider a solar cover reel or weight bags designed for pool covers. Never attempt to tie the cover down with makeshift ropes or heavy objects that could damage the pool liner or the blanket material itself. Always follow the manufacturer's recommendations for securing your specific pool cover model.

Is it safe to shock my pool with the cover on?

It is generally recommended to remove the solar cover when shocking your pool. High concentrations of chlorine can bleach the cover material, cause the bubbles to pop, and significantly reduce the lifespan of the blanket. After adding shock, allow the chemical levels to stabilize to the recommended range before replacing the cover. Always follow the instructions provided by your pool chemical manufacturer regarding the use of sanitizers and the safe deployment of covers to protect your equipment and ensure a safe swimming environment for all users.

How often should I clean my solar blanket?

You should clear debris from the cover as soon as you notice it to prevent organic material from sinking or decaying. A more thorough cleaning with mild soap and a soft sponge should be performed whenever the cover appears dirty or when you notice a buildup of residue. Regular rinsing with a garden hose helps maintain the material's clarity for better solar absorption. Keeping the cover clean is one of the most effective ways to extend its life and ensure it continues to perform its primary function of heat retention.

Can I leave the cover on all winter?

Solar blankets are typically designed for seasonal use during the warmer months and are not intended to serve as winter covers. Leaving a solar blanket on during the winter can expose it to freezing temperatures, heavy snow, and ice, which will likely cause the material to crack and the bubbles to fail. Always remove, clean, and store your solar blanket in a protected area during the off-season. Consult your pool manual for instructions on proper winterization procedures that are appropriate for your specific pool type and local climate.

Why is my cover losing bubbles?

The loss of bubbles is usually a sign of material degradation caused by UV exposure, chemical imbalances, or age. While all solar covers have a limited lifespan, you can slow this process by maintaining proper pool chemistry and storing the cover in the shade when not in use. If your cover is losing a significant number of bubbles, it is likely reaching the end of its functional life and will become less effective at retaining heat. At this stage, it is generally time to start planning for a replacement to maintain your pool's temperature efficiency.
