Automate freshwater replenishment, and say farewell to heavy lifting, unstable water parameters, and the need to frequently watch your water line.
Topping off evaporated water for our aquariums is a tedious but essential task that every hobbyist encounters to maintain stable specific gravity & salinity levels.
The HydroFill Ti ATO Controller takes advantage of your water`s conductive properties to complete a low voltage circuit and cause a control relay to actuate and replenish water as it evaporates. This departure from outdated float sensors, offers the latest automation in electronic sensing for precise accuracy, repeatability, and no-moving part reliability.
Customize your own "High and Low" set points to prevent constant On/Off cycling prone to single sensor design.
Sensors utilize rare earth neodymium magnets for stationary placement and simple out of the box installation. Small form factor makes it the ideal choice for nano to full size aquariums. Two Titanium electrodes are housed in each sensor for redundancy & consistent long-term performance in harsh marine environments.
Pair your auto top off with the industry`s first low voltage air lift pump specifically designed for ATO controllers. Engineered for high performance, this external positive displacement diaphragm pump, outputs up to 15 gallons per hour and max 5 feet of head. This self-priming pump is equipped with a built-in check valve to safeguard against back siphoning.
The HydroFill Ti diaphragm pump is the smart alternative when compared to submersible pumps, diaphragm pumps offer the benefit of safely running dry and are thermally protected against heat build-up.
Versatile design offers 3 options for pump placement: hang-on, cabinet mount, or simply place on noise dampening rubber feet.
The new Innovative Marine Hydrofill TI Reservoir offers several unique features that make it the most convenient ATO reservoir in the market!
The most unique feature is the pull-out fill drawer. No longer is it necessary to turn off your ATO, pull out the ATO pump, remove the ATO container, add water, lift the heavy and full ATO reservoir back in place, reinstall the pump and turn your ATO back on.
Now, just slide out the fill drawer, add water then close drawer: done!
