- Practical and Convenient: Perfect for business trips or travel, our water replenisher ensures your sea tank, fish tank, grass tank, or turtle tank maintains an adequate water supply, preventing any harmful water shortages. - Superior Performance: More efficient than float valves, our water replenisher operates without wiring or electricity, conserving space while delivering reliable performance. It automatically dispenses water from the bottle into the tank when the water level drops, thanks to the pressure difference. - Easy to Use: Designed for simplicity and enjoyment, just screw the compensator onto any standard water bottle, affix it to the tank, and adjust the spacing as necessary by removing the positioner. - Customizable Water Level: Adjust the water level by cutting the pipe to your desired length. For fish tanks taller than 40cm/15.7in, we recommend using multiple hydrators for optimal performance. - Secure and Adjustable Clip: The fixed clip slot provides stability, and the tank wall can easily support the vertical forces created by the weight of the water bottle, ensuring everything stays in place. Use Scenarios: 1. Ideal for aquariums where maintaining consistent water levels is essential for fish health—great for busy hobbyists. 2. Perfect for turtle tanks needing regular water adjustments while you're away for extended periods. 3. Practical for outdoor grass tanks where evaporation can lead to water loss, ensuring your plants remain hydrated even when you are not around.
