Natural Chemistry Cover Free (1 qt) 12 Pack - Reduce Evaporation

Our review of Natural Chemistry Cover Free (1 qt) 12 Pack finds it best for pool owners who want a low-effort way to reduce evaporation and retain heat without a physical cover. The product uses a mono-layer surface technology that forms an invisible film on the water and, according to the manufacturer and customer feedback, can cut evaporation by up to 85 percent and reduce heat loss by as much as 70 percent, making it a practical choice for backyard pools where saving water and heating energy is the primary goal.

Key Features

• Mono-layer technology: Forms an invisible surface barrier that conserves water by reducing evaporation across the pool surface.
• Reforming surface: Even when wind or bathers disturb the water, the product quickly reforms the liquid barrier at the surface to keep protection continuous.
• High retention: Excellent surface tension helps the product remain in place so you do not need to reapply constantly under normal conditions.
• Neutral pH: pH neutral formula is safe to use with standard pool chemistry without causing wide swings in pH balance.
• Easy dosing: Simple recommended dose per volume or surface area lets users apply it by squeezing the bottle over the pool surface using the measuring guide.
• Case quantity: Sold as a pack of 12 one quart (32-ounce) containers, useful for season-long maintenance or multiple pools.

Who It's For

This product suits residential and small commercial pool owners focused on conserving water and lowering heating costs, particularly where a physical cover is impractical or inconvenient. It is also a good match for anyone seeking an easy weekly maintenance step rather than a one-time installation.

Those who require a complete replacement for a solid or solar cover, or who want instant, measurable reduction in debris, should look elsewhere; this product targets evaporation and heat loss control rather than debris interception or full thermal insulation.

Pros & Cons

Pros

• Reduces evaporation substantially when applied correctly, helping conserve hundreds of gallons of water.
• Helps stabilize pool temperature and reduce heat loss, which customers noted as a clear benefit.
• Easy to use with bottle measuring guide and neutral pH that fits into routine pool maintenance.
• Sold as a case of 12, offering value for repeated applications or multi-pool use.

Cons

• Effectiveness can vary with conditions and some customers report mixed results on functionality.
• Does not act as a physical debris barrier or replace the insulating benefits of a solid pool cover.
