Prevent water shortages in your fish tank, aquarium, turtle tank, or any other water tank while you're away with our innovative water compensator. Key Benefits: - Automatic Water Refilling: Unlike traditional float valves, our compensator operates without wiring or power, ensuring hassle-free maintenance. - Compact Design: Takes up minimal space, making it a practical solution for any tank setup. - Easy Installation: Simply screw the compensator into a water bottle and attach it to your tank. No tools are required. How It Works: - When the water level drops, the shorter pipe is exposed, allowing water to flow into the tank automatically due to the pressure difference in the bottle. Compatibility: - Each compensator comes with 3 interchangeable nests to accommodate 4 types of tank thicknesses. - Compatible with standard 1L Evian bottles and other bottle types using the included adapter.
