- 20ft x 40ft EnergyGuard 500 micron GeoBubble™ Solar Cover
- Added UV and Chemical protection helps to increase the cover life span.
- Geobubble™ format gives a higher degree of heat transfer and reduces the breakdown of the bubbles.
- We would recommend this cover as the best option for use on indoor pools.
- Opaque black surface attracts maximum amount of heat transfer, and lack of light prevents algae growth.
- Ultimate 500 geobubble covers come with a 6 yr Pro Rata Warranty, which does not include shrinkage at up to 3%.
