Innovative Marine redesigns Hydrofill while drastically lowering price

by | Oct 7, 2015 | Advanced Aquarist | 0 comments

The new IM Hydrofill Ti ATO controller has been upgraded with corrosion-resistant titanium electrodes and a new PCB board that alternates the frequency being sent between each probe, creating a smaller chance for corrosion when producing the same volts.  The redesigned electrode sensor has been also physically slimmed down to make it easier to fit in tight spaces.

The best part? The Hydrofill ATO Ti’s price reduction from $199.99 to $69.99 (not a typo).

The new IM Hydrofill Ti Pump is also seeing a price reduction from $99.99 to $69.99.  The new price does not include the mounting bracket (previously included in the $99.99 price).  Aquarists may purchase the Hydrofill Universal Return Bracket as an option for $23.00. Customers now have the flexibility of purchasing only what they need.


A rundown of the Innovative Hydrofill ATO components (Innovative Marine supplied us with the following information):


HydroFill Ti – ATO Controller

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 This departure from outdated float sensors, offers the latest automation in electronic sensing for precise accuracy, repeatability, and no-moving part reliability.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.
