Innovative Marine AUQA Gadget HydroFill - Aquarium Auto Top Off System


Auto Top Off systems have been around for a while to help reef hobbyists automate the chore of topping off your system's water and maintain stable gravity and salinity levels. Auqa Gadget HydroFill ATO Controller system uses sensors attached with rare earth neodymium magnets for simple stationary placement. Small form factor makes it ideal choice for nano tanks but will perform for full size aquariums as well.

Place sensor on your tank for your high and low points of your water line. Sensor contain two chemically inert graphite electrodes for redundancy & consistent long-term performance in harsh marine environments as well as freshwater environments. Through sensing or not sensing the conductivity of the water, the sensors alert the controller to start or stop which prevents the on/off cycling common with single sensors.
