Tunze Osmolator Nano 3152 Auto Top Off

Why topping off your aquarium is so important
While we see low water level as an aesthetic nuisance, your aquarium inhabitants experience something dramatically different. Low water level due to evaporation means higher concentration of dissolved chemicals, including salt concentration. Sensitive marine fish, corals, invertebrates and other delicate species may be affected by this change in water parameters and osmotic pressure. The Tunze Osmolator ensures the accurate and safe compensation of evaporated water for osmotic stability in freshwater and saltwater aquariums.

The Tunze Osmolator 3155 is one of the safest ATO’s available. It utilizes an electronic eye sensor to monitor water levels and a backup float switch sensor with an optional audible alarm. The controller protects the quiet metering pump from running dry and reports an empty storage tank. Two magnetic holders for sensors and multiple mounting brackets included as well as a pump.

LED indicator lights the Osmolator will allow you to visually see if their are any issues with your top off system. 

Two technologies of water level monitoring, and built in safety back-ups.

The optical eye sensor will keep the water level very steady to keep the salinity from fluctuating in your aquarium.  The Osmolator does work well with kalkwasser.  

Max Head Height: 7.2 ft

Note: With any pump, kalkwasser can cause premature wear.  New pumps are available at a very reasonable price.
