Product Details
✓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.
✓Each compensator comes with 3 replaceable slots, suitable for 4 kinds of tank thickness. And an Evian 1L bottle will fit the threads well. For other bottles, you may use the adapter.
