The Tunze Osmolator has been our favorite aquarium auto top off since its release. It has proven to be ultra reliable and with it’s multiple failsafes near impossible to drastically overfill your aquarium if setup and installed properly (if the primary sensor fails there is a backup float and an alarm sounds, if the float fails the unit shuts down in 10 minutes until reset). With both it’s slow fill pump and precise primary electronic eye to measure water level in small increments changes in salinity in the aquarium are near non existent.

High-tech – for a reliable water level in the aquarium

In 1985 TUNZE^® invented the automatic refill system for aquariums. At that time, some people regarded this invention as a useless accessory….but they forgot something very important: sensitive aquarium animals need a constant osmotic pressure within their cells. The Osmolator^® (osmotic regulator) is very easy to install and provides its complete functionality in a single compact unit. Only the Osmolator^® is able to provide you with the necessary security and reliability, since it is based on the vast experience that TUNZE^® has been able to gather throughout the course of many years.
