FAQ
How does the negative pressure system work?
The system uses a vacuum created by a sealed chamber to draw water from the reservoir into the aquarium when the water level drops. It operates through gravity and does not require electricity.
Can this system be used with all types of aquariums?
It is compatible with standard aquariums that have a minimum capacity of 10 gallons. Ensure the tank has a stable water level and a clean, open top for proper function.
Is maintenance required for the system?
The system requires occasional cleaning of the water reservoir and checking the water level indicator. No internal parts need replacement under normal use.

Works well with my 20-gallon tank. I noticed a slight delay in refill during very hot weather, but otherwise it’s consistent and easy to use.
