Review on FZone Smart ATO Aquarium Auto Top Off Water Refiller System with Triple Sensors and Intelligent SPT Algorithm by Matt Duffy

I travel regularly for work and this unit does an excellent job of maintaining the water level so my Lily snorkel (with built in CO2 diffuser) works properly. It saves me headaches and anxiety when I'm not at home. The device knows when to stop because it can measure the water level in the tank with a sensor. I'm trying to hook up a water pump to a water source so that when I change the water it automatically pumps fresh water from the water source into the tank while I pump out the old water. It will be great.
