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.

Water level regulator with two sensors suitable for use in cabinet filters, in Comline® filters or directly on the edge of the aquarium. Scope of delivery: ready for mounting with power supply unit 12 V, metering pump, hose, magnet holder for sensors.

The Osmolator® will be supplied with low voltage pump, mounting magnets, tubing controller and power supply. You only need a reservoir and water.

The Controller 5017 displays all functions optically and sounds an alarm in case of failures.

Redundant security: the main sensor is a proprietary optic sensor. Should that fail a safety float switch shuts the unit off and sounds an alarm. Even if that fails safety circuitry shuts off the pump after 10 minutes.

An optical mini sensor recognizes the water level precisely
