Why does BRS recommend this?
One of the most popular ATO systems available. The JBJ A.T.O system is by far the most cost-effective way of utilizing a safe and consistent auto top off system. With multiple configurations, the JBJ A.T.O will fit almost anyone’s needs. With linkable brackets adjust and secure float switches, you will need to add your pump of choice, the JBJ ATO system is a great top off unit for reefers on a budget.
- Audible Alert
- Adjustable timer based Safety
- Multiple configurations
- Visual LED signals
- Includes float switches and brackets
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 and an Audible Signal alerts when in operation mode.
The kit includes commercial grade "Linkable Brackets" that can easily be adjusted to meet your height requirements, and securely positions your float sensors. No suction cups to 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. (Mode A- Example 1)
Note: No pump included. The pump will need to be able to refill the amount of evaporated water in just a couple of minutes. BRS suggest purchasing a pump that is just slightly larger and placing a ball valve to control the overall amount of flow. We suggest looking into the Sicce Syncra Silent line of pumps or the BRS 50 mL top off pump.

It sounds like the ATO discharge hose is positioned lower than the water level in your ATO reservoir which creates a siphon after the pump has been powered off. To fix this, you just need to raise the end of the ATO tube higher. For some reefers, it's easier to mount it on the very top of the sump or even up to the top of the display. :)
This will have a single outlet which a pump or possible water solenoid could be attached to. We do not currently have an option for water solenoid however if you find one option with an outlet control this controller can turn it on and off. Feel free to let us know if you have any further questions!
The max on time for the unit will be 14 minutes. Feel free to let us know if you have any further questions!
We are not aware of this feature being able to be turned off. You may want to contact the manufacturer to see if there is any adjustments. Feel free to let us know if you have any further questions!
We do not have voltages other than standard North American. Unfortunately our products are intended for use in the US and Canada only. Feel free to let us know if you have any further questions.
Any low flow pump will work with this ATO. I ave personally used our 50ml/min dosing pump but find that it had trouble keeping up with large systems. I moved to the Auqa Gadget HydroFill ATO Pump due to the fact that it can be run dry without any problems, its self priming and it won't back siphon.
Another great option would be a small submersible pump like the eheim 300 or sicce micra and micraplus
Keep in mind these pumps are rated for low head heights so if you are running the ATO hose from the ground to the top of your tank you will need to go a little bigger.
I hope this helps!
Have a great day :)
The vacuum pump is on the bracket at the top of the tank at lease 3 ft. higher then my R/O holding tank(no pump in here for the A.T.O.
Is the water in your storage container higher off the floor then the water in your sump? If so that would create a siphon when the pump turns on and water would continue to pass to the tank after it turns off (regardless of where pump itself is located).
Really just about anything will work in terms of the ATO itself, its more about how far and fast you need to pump water. The most common pump is the aqualifter pump which pumps slowly and only goes a couple of feet. Otherwise if you need to pump larger distances you could use something like the 50ml top off doser.
