🎯 Why Energy Guard is Different
The Algae-Fighting Advantage
Unlike clear or standard blue covers, the Energy Guard features a dark selective coating specifically engineered to:
✅ Block algae-promoting light wavelengths – Stops photosynthesis that feeds algae growth
✅ Allow heat-generating UV rays through – Keeps your water warm without the green tint
✅ Reduce chemical shock treatments – Fewer algae blooms mean less emergency chlorination
✅ Maintain water clarity – Enjoy sparkling pool water all season long
Perfect for pools that struggle with algae, especially those in shaded areas, surrounded by trees, or in humid climates where algae thrives.
🔥 Advanced GeoBubble Technology
What Makes GeoBubble Superior?
The patented GeoBubble design isn’t your typical bubble wrap cover—it’s engineered for performance:
25% Longer Lifespan – Interconnected bubble structure resists tearing and degradation
500 Micron Thickness – Optimal balance of durability and heat transmission
Enhanced Insulation – Air pockets trap heat like a greenhouse over your pool
UV & Chemical Resistant – Withstands harsh sun exposure and chlorine contact
How It Works
- Dark coating blocks visible light → Algae can’t photosynthesize
- Selective transmission allows UV rays → Water heats naturally by up to 8°C*
- Bubble structure traps heat → Prevents up to 98% of evaporative heat loss
- Sealed air pockets insulate → Keeps warmth in overnight and on cloudy days
