Hydor USA Hydor Smart Level Control - water level management system

Smart Level is the new versatile fully electronic water level controller designed by Hydor. Smart Level safely and easily handles the aquarium and sump water level due to evaporation. Designed to be used in the many different conditions that exist in the marine and freshwater aquarium environment. Smart Level technology reduces the problems related to lime scale deposits, bacterial film, and wave action, which ensures the continuous, safe, and regular functioning of the Smart Level control.

For the SMART LEVEL Control, all types of pumps can be used, up to a maximum power of 50W. Choose a pump with a flow and head suitable for the type of use. Note that it is best to use a pump that tops off slowly within 10 minutes (maximum topping-off time).

Top-off pump required and sold separately.

Units now include a polarized socket and will accept a standard 2-prong plug.

“Nice ATO”
4.5
4.5
I've had this ATO installed alongside my 29g BioCube for almost two years, and it has worked great the entire time. I do appreciate the audible alarms to let me know if there are any issues with the ATO that require my attention. I'm using it with an Aqua Lifter pump and the combo is perfect for my ...Read More

I used mine (and it worked very well) for about 10 months. It has since failed. Nothing changed, it just stopped working. It alarms at all times no matter what sensors are covered.

So far the ATO has worked flawlessly. I really like the display letting me know if we are on the Low side or high. Either way the audible alarm provides a warning.

“Not Sending Water”

“Awesome!”
5
5.0
Now this is my first auto-top off unit and I must say for the price I am very impressed. It works very well and it's reliable. Hydor always delivers. The only thing that bugs me from time to time is that if the sensor isn't level to the water like if it's tilted just a bit it starts to beep until ...Read More
