FAQ

Pool Maintenance — FAQ

Can I use this cover on a saltwater pool?

Yes, these solar covers are generally compatible with saltwater pools. However, it is important to monitor your pool's salt and chemical levels closely. High concentrations of salt or improper chemical balancing can potentially accelerate the degradation of the plastic material over time. Always ensure your pool chemistry is maintained within the recommended parameters provided by your pool professional. If you notice any signs of premature wear, such as the material becoming brittle or the bubbles thinning, it may be time to rinse the cover more frequently or check your chemical levels to ensure they are not exceeding the manufacturer's suggested limits for pool equipment.

How do I trim the cover to fit my pool?

Most of these solar covers are designed to be cut to size. To do this, place the cover on the water surface with the bubbles facing down. Allow it to settle for a few hours to smooth out any wrinkles. Use a sharp pair of heavy-duty scissors or a utility knife to trim the excess material along the edge of your pool. It is recommended to leave a slight overlap or cut it slightly larger than needed initially, as the material may shrink slightly over time. Always exercise caution when cutting to avoid damaging the pool liner or the cover itself.

Does the cover need to be removed when shocking the pool?

Yes, you should always remove the solar cover before adding shock or high concentrations of chemicals to your pool. The concentrated chemicals can cause immediate and permanent damage to the cover, including bleaching, thinning, and cracking. Wait until the chemical levels have returned to their normal, safe range before placing the cover back onto the water. This practice is essential for protecting your investment and ensuring that the cover continues to provide effective heat retention and debris protection throughout the entire swimming season. Following this simple rule will significantly extend the life of your cover.

Will this cover prevent algae growth?

While a solar cover helps by blocking sunlight and debris, it is not a substitute for proper pool sanitation. Algae can still grow if the water chemistry is not properly balanced or if the sanitizer levels are too low. The cover's primary function is to retain heat and reduce evaporation. You must continue to maintain your regular pool filtration and chemical treatment schedule to prevent algae. Using a solar cover can actually make your chemical routine more efficient by reducing the amount of chemicals lost to evaporation, but it does not eliminate the need for regular maintenance.

How long should I expect the cover to last?

The lifespan of a solar cover depends on several factors, including the mil thickness, your local climate, how often it is used, and how well it is maintained. Generally, a 12-mil or 16-mil cover will last longer than a 10-mil cover due to its increased durability. Proper care, such as rinsing it regularly, storing it out of direct sunlight when not in use, and keeping chemical levels balanced, will significantly extend its life. While there is no fixed expiration date, most owners can expect several seasons of use if the cover is handled with care and stored properly during the off-season.

Can I use a reel with these covers?

Yes, these solar covers are compatible with most standard pool cover reel systems. Using a reel is highly recommended, especially for larger pools, as it makes the daily process of covering and uncovering the pool much easier and helps prevent damage from dragging the cover across the deck. When choosing a reel, ensure it is sized correctly for the width of your pool and the weight of your specific cover. A reel also provides a convenient way to store the cover neatly, which can help prolong its lifespan by preventing unnecessary creasing or tearing during handling.

Does the bubble side face up or down?

The bubbles should always face down, touching the surface of the water. This design allows the air trapped inside the bubbles to act as an insulator, which is crucial for heat retention. The flat side of the cover should face upward toward the sun. This orientation maximizes the solar absorption while providing the necessary thermal barrier to keep your pool water warm. If the cover is placed with the bubbles facing up, it will not be as effective at retaining heat, and the bubbles may be more susceptible to damage from direct environmental exposure.

What should I do if the bubbles start popping?

If you notice bubbles popping or detaching from the cover, it is typically a sign of age, excessive chemical exposure, or damage from intense UV rays. While individual bubbles popping is normal as the cover reaches the end of its lifespan, widespread damage suggests it is time to replace the cover. To delay this, ensure that your pool chemistry is always balanced and that you are storing the cover in a shaded area when it is not in use. Once the bubble structure is significantly compromised, the cover will lose its ability to effectively insulate the water.
