Buying guide

What to look for

Verify Exact Pool Dimensions

Before purchasing, measure your pool accurately. While 18x36 is a standard size, coping and deck configurations can impact the fit. Ensure you account for any rounded corners or steps that might require trimming. Some covers can be cut to fit, but always verify this feature in the product description. A cover that is too small will fail to retain heat or prevent evaporation, while an oversized cover can be difficult to manage and prone to damage from wind or improper folding.

Understand Material Thickness

The 'mil' rating indicates the thickness of the solar cover. A 16 mil solar pool cover 18x36 is generally more durable and provides better heat retention than a 12 mil or thinner option. Consider your local climate; if you live in an area with cooler temperatures or high winds, a thicker material is often a better long-term investment. Thinner covers are lighter and easier to handle but may have a shorter lifespan under harsh conditions.

Assess Ease of Handling

Consider how you plan to put the cover on and take it off. A 18x36 cover is significant in size and can be heavy when wet. If you do not have a pool cover reel, you may need a second person to help with daily removal. Read user feedback regarding weight and manageability to ensure the product you choose aligns with your physical capabilities and the time you have available for pool maintenance.

Check Warranty and Support

Review the warranty terms provided by the manufacturer. Understand what is covered—such as material defects—and what is excluded, like normal wear and tear or damage from improper chemical use. A longer warranty period can be an indicator of product quality, but always read the fine print. Ensure the manufacturer provides clear instructions for installation and maintenance, as this will be your primary resource if you encounter issues after purchase.

Evaluate Solar Efficiency Needs

Think about your primary goal. Are you looking for maximum heat gain, or is evaporation control your main concern? Solar covers work by trapping the sun's energy, so the color and bubble design matter. Darker blues often absorb more heat, while clear or transparent covers may allow more light to penetrate. Research the specific technology used in the cover, such as bubble shapes, to see if it aligns with your heating goals.

Review Compatibility Requirements

Check if the cover is specifically designed for your pool type, whether it is above-ground or in-ground. Some covers are universal, but others have specific anchoring systems or edge reinforcements that might not work with your pool's design. Verify the listing details to confirm the cover is compatible with your pool's structure and any existing equipment, such as ladders or skimmers, that might interfere with the cover's placement.

Consider Seasonal Requirements

Determine if you need a solar blanket for summer heating or a winter cover for off-season protection. Solar covers are not designed to support the weight of heavy debris or snow during winter. If you live in a climate with cold winters, you may need two separate covers. Investing in the right type of cover for the current season is critical for both the safety of your pool and the longevity of the equipment.

Setup, use, and maintenance

Regular Debris Removal

Keep your pool cover free from leaves, twigs, and dirt. Accumulation of debris can lead to mold growth or premature material degradation. Use a soft-bristled brush or a leaf net to gently clear the surface before removing the cover. Avoid using sharp tools or pressure washers, as these can puncture the bubbles or tear the fabric. Consistent cleaning prevents organic matter from decomposing on the cover, which could otherwise leach into your pool water and disrupt your chemical balance. Always ensure the cover is completely dry before folding it for storage to prevent mildew buildup. Regular maintenance not only extends the product lifespan but also ensures that sunlight can penetrate effectively for maximum solar heating efficiency throughout the season.

Chemical Balance Monitoring

Pool covers can trap chemicals, potentially leading to higher concentrations near the water surface. Regularly test your water chemistry and follow manufacturer guidelines for chemical applications. Avoid applying concentrated chemicals directly onto the cover material. If you need to shock the pool, remove the cover entirely and allow the water to circulate for several hours before replacing it. High levels of chlorine or other sanitizers can degrade the plastic material of solar blankets, causing the bubbles to become brittle or separate. Always check your pool manual for specific recommendations on chemical usage while using a cover. Maintaining proper pH and alkalinity levels is essential not just for the water quality, but also for preserving the integrity of your solar pool cover.

Proper Folding Techniques

When removing your 18x36 pool cover, avoid dragging it across abrasive pool decks or coping. Use a pool cover reel whenever possible to minimize stress on the material. If you must fold it manually, do so gently to avoid creasing or damaging the solar bubbles. Store the folded cover in a shaded area away from direct sunlight, as UV exposure can cause the material to break down rapidly when not in use. Ensure the storage area is clean and free from pests that might chew on the plastic. Proper handling during the removal and storage process is the most effective way to prevent accidental tears and maintain the structural performance of your cover for many years.

Seasonal Storage Preparation

At the end of the swimming season, thoroughly clean your cover with mild soap and water, then rinse it well. Allow it to air dry completely in a shaded spot. Once dry, fold or roll the cover neatly and store it in a cool, dry location. Avoid storing the cover in areas subject to extreme temperature fluctuations, as this can cause the plastic to become brittle or warp. If you have a winter cover, ensure it is secured tightly according to the manufacturer instructions to prevent wind damage. Proper seasonal storage prevents the material from sticking together or developing cracks, ensuring that your cover is in optimal condition when you are ready to reopen your pool for the next season.

Routine Inspection Protocols

Perform a visual inspection of your cover at least once a month. Look for signs of wear, such as thinning material, popped bubbles, or fraying edges. If you notice small tears, address them immediately with a dedicated pool cover repair kit to prevent further damage. Check the attachment points or weights if you are using a winter cover to ensure they remain secure. Early detection of minor issues allows for simple repairs, avoiding the need for a full replacement. By staying proactive, you ensure the cover continues to provide the intended heat retention and evaporation control. Keep a record of your inspections to track the cover's condition over time, helping you decide when it might be time for a professional assessment.
