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.
