Bestway Flowclear 12' Solar Pool Cover — 12 ft floating heat-retaining cover, reduces evaporation & debris

The Bestway Flowclear 12' Solar Pool Cover is a floating, heat-retaining cover designed to keep warmth in your 12-foot above-ground pool while reducing evaporation and blocking leaves and debris.

Designed for Bestway Fast Set™ and Steel Pro™ pools with a 12' (3.66 m) diameter, this Flowclear solar cover creates a greenhouse effect on the water surface. The lightweight material lies on top of the pool, trapping solar energy and slowing heat loss overnight. At the same time it limits water loss from evaporation and keeps floating debris out — helping you spend less time on maintenance and more time swimming.

How does the solar cover help keep pool water warmer?

The cover’s bubble-textured material captures sunlight and transfers that heat into the water while forming an insulating layer that reduces heat escaping after sunset. It floats directly on the surface, so energy transfer is efficient and immediate.

• Bubble-cell design converts sunlight to heat for the water.
• Insulates the pool surface to slow overnight heat loss.
• Direct contact with water improves heat transfer efficiency.

Will this cover reduce water evaporation and chemical loss?

Yes — by covering the water surface the sheet limits air exposure, which significantly reduces evaporation caused by wind and sun. Lower evaporation also helps preserve pool chemicals and reduces how frequently you need to top off water.

• Drastically lowers water loss from wind-driven evaporation.
• Shields surface water from direct UV exposure that degrades chlorine.
• Float-on design maintains coverage even with small surface movement.

How effective is the cover at keeping debris out and easing maintenance?

The sheet blocks leaves, twigs, and airborne debris from entering the pool, reducing time spent skimming and vacuuming. Because it rests on the water it prevents easy entry of larger debris while still allowing normal filtration when partially removed.

• Stops most common outdoor debris before it reaches the water.
• Reduces frequency of skimming and filter backwashing.
• Quick to remove and replace for regular pool use.

What size pools is this cover compatible with and how does it fit?

The cover is sized to fit Bestway 12' Fast Set™ and Steel Pro™ pools, with an effective diameter of roughly 11 ft. 8 in. It’s intended to float on the surface rather than attach with straps, so installation is fast and tool-free.

• Recommended for 12' (3.66 m) above-ground Fast Set and Steel Pro pools.
• Approximate cover diameter: 11 ft. 8 in., floats on water surface.
• Simple placement and removal — no hardware required.

Who is this for?

The Bestway Flowclear 12' Solar Pool Cover is ideal for owners of 12-foot above-ground pools who want an affordable, easy-to-use way to retain heat, cut evaporation, and keep debris out between swims. It suits homeowners looking to extend their swimming season, reduce water and chemical waste, and lower routine maintenance time without complicated installation. If you have a Bestway Fast Set™ or Steel Pro™ 12' pool and want a straightforward thermal and protective layer, this cover delivers practical, low-effort benefits.
