SSR SSRA 100 Solar Sun Rings Pool Water Heater w/ Anchors (3 Pack)

What the Solar Sun Rings three-pack is

This exact ASIN is a Solar Sun Rings floating disc pack, not a panel heater or full solar cover. The listing describes three 5-foot round blue rings made from two layers of U.V. resistant vinyl; the clear upper layer directs sunlight to the blue lower layer.

Decide if discs fit your goal

• Each ring includes six magnets used to attach rings together, so plan layout and connection before adding more rings.
• The seller states these discs are not a solar cover or replacement for one; if you need nighttime heat retention, consider separate insulation such as a blanket.
• Inflate carefully: the listing warns against over-inflating and says they are not flotation devices.

If your goal is to hold heat overnight, note that rings do not cover the entire surface; the listing recommends additional insulation. Use it as a passive heating aid. Amazon product listing
