About This

• Uses UV Light Directly — Not Indirectly — Other "solar pool sanitizers" use sunlight to power metal ionizers or generate electricity to create UV light mechanically. Our BioPhotonX UV light conversion film directly converts UV sunlight into sanitizing energy at the point of contact with your water. Pure solar-to-sanitation efficiency.
• Reduce Chlorine & Bromine by 50%+ — Maintain clean, balanced water while cutting chemical use in half. Enjoy a more comfortable swim with less odor, irritation, and dryness.
• Natural, Gentle & Eco-Friendly Solution — No metals, no additives, and no harsh chemicals. Just a clean, sustainable water care method that’s safe for families, pets, and the environment.
• Covers hot tubs & swim spas Up to 10,000 Gallons — Use TUBE 2-pack for 15,000 gallon pools;. TUBE 3-pack for 30,000 gallon pools; TUBE 4-pack for 40,000 gallon pools.
• Simple “Drop-In” Use, Minimal Maintenance — Balance your water, place the TUBES in your hot tub/swim spa, and let the sun do the work. Gradually reduce chemical use over a few weeks—no complicated setup required. Continues to work even with hot tub cover on for multiple days.
• Making Water Care Safer — Made in the USA, Card On Guard and our BioPhotonX UV light conversion film technology are finding ways to leverage solar energy to reduce the use of chemicals everywhere.
