When you are on a business trip or traveling, use our water compensator to avoid water shortage in your fish tank, aquarium tank, tortoise tank, or other tanks. Better than a float valve, no wiring or power required, takes less space. Easy to use, practical and interesting. Just screw the compensator to a water bottle, then stick it to the tank. When the water level drops to reveal the shorter tube, the water in the bottle automatically flows into the tank due to pressure difference.
