Frequently Asked Questions

Q: How does the automatic water level controller work for aquariums?

A: The Kesoto Auto Water Level Controller uses a pressure-difference principle. When the water in your fish tank or aquarium drops below the set level, the float mechanism triggers the device to allow water to flow in from an attached reservoir or water bottle — no electricity or pumps needed. Once the water reaches the preset level, the flow automatically stops.

Q: Is this water level controller compatible with all types of fish tanks and water tanks?

A: Yes! This adjustable auto water filler is designed for wide compatibility. It works with standard aquariums, turtle tanks, freshwater reservoirs, and most containers or water bottles used as a top-off reservoir. It is especially effective for small to medium-sized tanks.

Q: Do I need any tools or electricity to install this auto water filler?

A: No tools or electricity are required. The device is simple to set up — just position it in your tank, attach your water supply container, and adjust the float to your desired water level. The pressure-difference mechanism handles everything automatically from there.
