A: This aquarium automatic water level controller is compatible with freshwater fish tanks, marine/reef aquariums, and commercial seafood holding tanks. It is designed to work with any setup that uses standard 1/4" PE pipe tubing.
Q: What pipe size does this aquarium auto-fill kit require?
A: The floating ball valve kit is designed to work with 1/4" PE (polyethylene) pipe. It also includes both a 1/2" female/male connector and a water tank connector for versatile installation.
Q: Is the floating ball valve safe for fish and aquatic life?
A: Yes. The floating ball is made from food-grade POM (polyoxymethylene) material, which is non-toxic and safe for use in aquariums with live fish and other aquatic animals.
Q: How does the automatic water level control system work?
A: The system uses a buoyant floating ball attached to the valve. As the water level drops due to evaporation or usage, the ball lowers and opens the valve to allow fresh water in. Once the water reaches the set level, the ball rises and closes the valve — maintaining a consistent water level automatically.
