Stop being a slave to your tank!

inTank has used this unit for three plus years!  This unit is the perfect auto top off for any AIO system.  No more daily top offs, no more finding a babysitter you can finally leave the tank for days without worry.

The JBJ Automatic Top-Off (A.T.O.) Water Level Controller is a professional grade product that automates refilling evaporated water. The All-New A.T.O (Automatic Top Off) device is the most advanced water level controller system on the market. Lifting heavy buckets and spilling water is now a thing of the past. Maintaining stable salinity and specific gravity are no longer a problem since the A.T.O. will refill as soon as the water level drops. The A.T.O. will keep all salt levels at consistent parameters, ensuring an optimal environment for your tank inhabitants.

Does not include a pump.  Depending on height being pumped inTank recomends the Maxi Jet 900 or 1200.  See head height on pump description.

  Float Sensors
The A.T.O. is equipped with (2) float sensors that activate within seconds when your water level drops and automatically refills your sump or tank until it reaches your desired set point. Each float sensor has been designed with an exterior guard preventing snails & hermit crabs from attaching to the sensors.

Electronic Controller Module
Our state-of-the-art electronic controller allows for (2) modes of operation with a total of (3) different set up scenarios, allowing you more choices for installation for your unique set up. Our compact controller also incorporates a visible L.E.D. panel + our innovative Audible Signal alerts when in operation mode.

Linkable Brackets
Your professional kit includes commercial grade "Linkable Brackets" that can easily be adjusted to meet your height requirements, and securely positions your float sensors. Many competing brands use inferior suction cups that are temporary that can lead to disastrous water spillage.

Pump Safety Protection
The A.T.O. automatically stops power to your return pump in your reservoir, in the event that your reservoir is low on water. This safety feature prevents pumps from running dry and failing.
