JBJ ATO Water Level Controller.


Tired of lifting heavy buckets to refill sumps or tanks due to evaporation?

There is finally 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.

Advanced Features:

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 LED 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.

* Power Supply for Pump Capacity: 2A
* Dimensions (L x W x H): 1.5" x 2.75" x 4"
* Weight: 2lbs
* Pump: (Not Included)

weekend pass
With three reef tanks I found it difficult to get away for more then one or two nights at a time. The three auto top offs for the tanks allow a degree of freedom from lifting water every day, as well as maintaining a greater degree of stability in the salt water osmolarity. The corals themselves seem to be doing better. The sump levels are consistent with only a seven to eight mm. variation. So far the auto top off has proven reliable.Very happy with them.
