Card On Guard contains a lightweight, thin and self-sustaining solar cell that captures, stores and re-emits UV and infrared light. Floating in a pool vertically, it inhibits bacterial and fungal growth in a natural way. It can replace 50 to 100 per cent of traditional pool chemicals. Seen from above, the pool accessory is reminiscent of a shark fin, while its shape ensures maximum direct contact with both light and water. Both sides of the solar cell are almost entirely submerged, which guarantees protection.
