Surface Debris Management

A liquid solar cover functions best on a clean water surface. Debris such as leaves, twigs, and insects can disrupt the thin film created by the product, potentially reducing its effectiveness. Maintain a rigorous skimming and vacuuming routine to remove floating contaminants before they sink or break the surface tension. If your pool has a high leaf load, consider using a skimmer net daily. While the liquid cover is designed to be harmless to pool equipment, heavy debris can clog filters and skimmers, which in turn affects water circulation.

Filter System Inspection

Your pool filtration system is essential for distributing the liquid solar cover. Ensure that your pump and filter are operating correctly to allow the product to circulate throughout the pool. If your filter pressure gauge indicates that the system is struggling, perform a backwash or clean the filter cartridges as recommended by your equipment manual. A poorly functioning filter can lead to uneven distribution of the product, resulting in areas of the pool that are not protected.

Professional Seasonal Audits

While liquid solar covers are user-friendly, an annual professional audit of your pool system is recommended. A technician can verify that your pump, filter, and chemical distribution systems are working in harmony with your chosen maintenance products. They can also provide advice on whether the specific brand of liquid cover you are using is the most effective for your local climate and pool usage patterns.
