Currently the best auto top off (ATO) solution for nano aquariums. This ATO has a small in tank footprint making it perfect for sumps with limited space, rear chambers of AIO tanks, or even discretely place in the display tank. And with a small diameter pump (just under 2"), it will fit into most containers comfortably.

What about a failsafe? Well the Nano Osmolator accounts for that too, with a maximum run time of 1.8 to 3 minutes (adjustable), even if the float switch sticks (unlikely) your tank will only receive that amount of top up - 1.5-3L.

For small aquariums, a stable osmotic balance is important, because they are particularly sensitive to constantly changing salt concentrations. The Osmolator® nano which was specifically designed for this, is a water level controller with only a single sensor and is equipped with a processor-based controller that protects against overdosing. It is suitable for nano aquariums or small aquariums up to 200 liters (55 USgal.). The sensor with magnetic holder is light-protected and can be positioned at any desired location on the glass panel.
