Replenish Evaporated Water... with Confidence!
The WaveReef ATO System is an easy-to-use lift pump and sensor combo, providing peace of mind by automatically replenishing evaporated water in your aquarium. It utilizes a dual optical sensor setup: one to control the refill lift pump and another as a safety feature to prevent overflows. The WaveReef FATO-200 & FATO-303M ATO systems are smartly designed, with no moving parts to fail, ensuring reliable operation in both freshwater and marine aquariums.

FATO-200 & FATO-303M Operation

When the water level drops below the optical sensor (2), it activates the pump, indicated by a blinking blue light, and the water level rises to the normal state.
Once the normal level is reached, the blue light remains solid.
A safety level sensor (1) shuts down the pump if a malfunction occurs, with a red light flashing to indicate an issue.
