The Robo-Tank DIY ATO System is a high quality, highly accurate, full featured customizable auto top off system for your aquarium and has 5 layers of security to provide redundancy and protect against floods or other catastrophes. It can be used out of the box as a standalone system or connected directly to an Arduino or Raspberry Pi and integrate into your own system using I2C communications.

For maximum protection the ATO system can be used with up to 4 sensors which is great for travelers, it has an auto learning emergency timeout timer and even monitors the energy your pump is drawing on the heavy duty DC pump port to anticipate failure. All this gives you an extremely safe system and will keep the water in your tank and off the floor. You can also add an optional mechanical float valve that stops water flow adding an extra of protection.

Three of the sensor ports support a variety of readily available sensors including optical, non-contact, float switches and more. Sensor port 3 is a multi-use port and can be used as an additional backup for the ATO or setup to monitor the reservoir level. In addition there's one port dedicated to a float switch which is completely independent of the ATO system and only for an emergency.

It's also loaded with customizable features such as manually setting a maximum pump run-time, adjusting the start/stop delays, the pump speed, the alarm volume and much more. The ATO system is equipped with a loud adjustable buzzer for alarms, indicator LEDs and a convenient multi-use button on the side of the case.

Reliable, Strong, Functional


The Robo-Tank Auto Top Off is built using high quality components and fully assembled and tested here in Alberta, Canada. Two things are very important to me, your satisfaction and my reputation, I'm always available to help or answer any questions and greatly appreciate your support.

The auto top off is housed in a strong 3D printed case using high quality PLA filament keeping everything protected. It has a silkscreen covered faceplate giving it a clean look and easy to manage pluggable screw terminal connectors.

All the features you expect and more, multiple sensor types, customization, convenient indicator LED's, useful push button and a couple USB ports if you want to integrate the ATO into your own system or create a web app to access away from home, so many possibilities.


Quality Accessories


The Auto Top Off is available as a complete plug and play kit that can be installed in less than 5 minutes or in a DIY form to ease your budget. The accessories included in the kit are good quality and I've been selling them for years. As a general rule everything from components to accessories are over-rated so nothing is overworked, many kits come with too small pumps, weak power supplies and so on.


Maximum Auto Top Off Protection

The Robo-Tank ATO system was designed with redundancy in mind to not only protect your floors but all your beloved livestock as well. The ATO can be used with 2 or 3 selectable sensors and 1 primary emergency backup float switch. Sensor 3 can be used to monitor the reservoir (the default setup) or using the 3rd sensor for the auto top off is a good choice if you travel or away from your aquarium for long periods as it adds an extra layer of redundancy allowing the ATO to function with more failures.

Along with optical sensors the auto top off will automatically generate a maximum allowable run-time that works on small and large size aquariums. This will shut down the water pump if the sensors fail however you can opt to manually set it down to the second. An additional trimer also starts when the pump turns on and automatically shuts down the ATO when 10 minutes pass.

It doesn't end there though, in the unlikely event the auto top off becomes unresponsive it will automatically reset itself or the final Emergency Backup Float Switch is guaranteed to turn it off as it doesn't rely on the electronics or code and will prevent water from overflowing your aquarium.

One more small feature yet just as important, the auto top off is continually monitoring the energy being consumed by your DC water pump. If it detects the pump isn't drawing what it should the alarm will sound so you know to clean or replace your pump. This ensures you always have a perfectly functioning water pump while other auto top off systems only warn you when it's too late and your water has dropped to levels that have consequences. If you replace the pump simply cycle the auto top off power source and you'll be back in business.


Advanced Alarm Management

The auto top off module has a loud internal buzzer and you can adjust the volume, it will sound if anything fails so you can attend to the problem.

If an alarm event occurs the buzzer won't sound for X number of minutes which you can adjust, the default is 10 minutes. The pump will still be turned off immediately, only the alarm will be delayed. This is good for suppressing alarms and saving your ears during maintenance or when you feed your fish.

If the delay expires the alarm will continue to sound until you reset the auto top off by pressing the push button on the side of the case. The beep pattern emitted will indicate which sensor is controlling the auto top off.


Convenient Push Button

On the side of the auto top off module there's a small push button that can be used for a few events. When an alarm is sounding the buzzer will continue to beep until you press this button momentarily which will reset it.

If you press and hold it for 1.5 seconds the auto top off will enter/exit a maintenance mode which will turn off the auto top off and disable the system while you do a water change. This will auto time out after 6 hours or you can manually exit.

If you press and hold the button for 3 seconds the ATO will enter/exit a test mode, this will simply disable all the delays so the ATO responds in real-time. This will auto time out after 60 minutes or you can manually exit the same way you entered.

And finally if you press and hold the button for 10 seconds all the default settings the ATO was shipped with will be restored.


Auto Top Off Customization

Every Aquarium is different, that's why the Robo-Tank auto top off settings and sensors can be customized to your preferences, maybe your setup is better suited with Non-Contact water sensors or float switches.

The default settings are acceptable for all tank sizes but as an example if the system runs too often or fast for your liking seemly adjust the appropriate settings to fine tune the system.

To adjust the settings you simply remove the back lid and use the 3 push buttons along with the RGB LED to navigate the menu and adjust the settings, refer to the user manual.

There are 8 settings in total, click to view the details.

Setup Option 1       = Sensor 3 Function - Default is “Monitor the Reservoir”

This allows you to change the function of Sensor 3 and has 2 available options: It can be set to “Monitor the Reservoir” or, as a “3rd auto top off Sensor” for the regular auto top off function.

Setup Option 2       = Alarm Volume - Default is “100%”

With this setting you can control how loud the audible alarm is, there are 7 different volumes to choose from.

Setup Option 3        = Alarm Delay - Default is “10 Minutes”

This allow you to control how many minutes delay is added before an alarm sounds. When an alarm triggers the pump will still be turned off immediately but the alarm won’t sound until the delay has expired. This can be set between 0 minutes and 60 minutes in 1 minute intervals.

Setup Option 4        = Pump Voltage - Default is “12 Volts”

This setting allows you to change the output voltage of the DC pump port which will slow down your pump. For example you have a 12v DC pump connected but it runs to fast you can adjust this to slow it down. Only change this if your pump shows a range of voltages such as 6v-12v. There are 6 voltages to choose from, 3.8v, 5v, 6v, 8v, 10v and 12v.

Setup Option 5       = Sensor 1 Sensitivity Level - Default is “Medium”

This setting lets you adjust the sensitivity level of Sensor 1 but the effect is only seen if you use an optical sensor. If you want a smaller or larger volume top off set this accordingly. There are 3 different settings to choose from, Low, Medium and High.

Setup Option 6      = Start Delay in Seconds - Default is “5 Seconds”

This setting adds a delay before the auto top off switches on allowing time for the sensor to stabilize so the pump isn’t constantly turning on/off because of waves. Using the 5 second default would mean the sensor must sense a low water level for at least 5 consecutive seconds otherwise the timer will reset until this is achieved. This can be set between 1 second and 60 seconds in 1 second intervals.

Setup Option 7      = Auto Calculate Maximum Run-time - Default is “On”

If this is turned on the system automatically calculates the Maximum Run-time which switches off the ATO if the timer expires. This will work on any size aquarium but is designed to work with the Robo-Tank Sensor Bracket and optical sensors. If you setup is different it’s better to turn this “Off” and use the manual mode. If Auto Calculate is turned off the settings in “Setup Option 8 and 9” are used to determine the Maximum Run-time.

Setup Option 8       = Maximum Run-time Minutes - Default is “5 Minutes”

This setting is used if “Setup Option 7” is off and goes together with “Setup Option 9”. It’s used to manually set the maximum run-time for the auto top off pump. The system takes the minutes and seconds and sets a total allowable run-time. For example if you set it to 4 minutes and 10 seconds that’s how long it can run before switching off the ATO. This can be set between 0 minutes and 10 minutes in 1 minute intervals.

Setup Option 9        = Maximum Run-time Seconds - Default is “0 Seconds”

This setting is used if “Setup Option 7” is off and goes together with “Setup Option 8”. It’s used to manually set the maximum run-time for the auto top off pump. The system takes the minutes and seconds and sets a total allowable run-time. For example if you set it to 1 minute and 37 seconds that’s how long it will run before switching off the ATO. This can be set between 0 seconds and 59 seconds in 1 second intervals.


LED Indicators

Never be left guessing, the DC pump port has a convenient LED indicator so you always know if the pump is on or off, plus there's two additional LED's on the side. One lights up when the auto top off module is powered and the other LED indicates the mode the auto top off is operating in.




Water Pump Energy Monitoring

The Robo-Tank Auto Top Off System is constantly monitoring the energy being consumed on the DC pump port, if it detects anything out of the ordinary the alarm will sound so you can attend to it. When you power up the auto top off it begins monitors the system for about a day to learn the pattern of your pump. This is useful for sniffing out pumps that are becoming less efficient and could become an issue, the auto top off continues to function as normal until it shuts down and the alarm will sound.



Robo-Tank Auto Top Off Compatibility

Although this is a standalone product it's also compatible with any micro-controller that has an I2C bus such as any Arduino or Raspberry Pi. There will be an open source Arduino library available in the future that will allow you to receive data from the auto top off, update all the settings, receive the amps being drawn on the DC pump port and other settings not mentioned. This allows you to fully integrate the auto top off module into your own system and monitor it over the Internet from anywhere in the world.


2 Year Warranty

Like the industry leading competitors you can be at ease with your Robo-Tank Auto Top Off System as its comes with a 2 year warranty, if the auto top off module fails simply contact us and ship it back and it'll be repaired or replaced in a timely fashion. Please note the warranty doesn't cover the sensors, abuse or water damage.
