Tunze Osmolator 3155 - Salty Critter

Water level regulation with static sensor

In 1983 already, TUNZE Aquarientechnik introduced the first water level regulator (Osmolator) to aquarism. TUNZE Aquarientechnik has developed a new generation of osmotic regulator with static and compact sensor in IR technology for constant water level regulation in freshwater and saltwater aquariums. It ensures osmotic stability in freshwater and saltwater aquariums by precisely and regularly compensating the evaporated water.
Osmolator Universal 3155 can be used as a supplement in cabinet filter plants, COMLINE quick-run filters or directly on the tank edge

The precise water level is ensured by a non-wearing optical sensor and a transistor switch without any moving parts. This sensor is insensitive to soiling, light or magnetic fields.
Its “automatic eye” recognizes the water level precisely, even small waves or level variations cannot irritate the unit.

An independent safety sensor with a separate power supply circuit and relay control ensures reliable overflow protection.

An electronic time controller and current limiter for the pump connected result in a higher operational safety. This unit protects the metering pump against running dry and reports an empty storage container.

All functions are clearly displayed by LEDs; safety messages are also indicated by acoustic signals.

The osmotic regulators are all operated at safety extra-low voltage.

Tunze Calcium dispenser
(5074.000)

The addition of lime water is another method to increase the calcium in saltwater aquariums. The calcium hydroxide is dissolved in a separate tank by means of the water jet of the metering pump in the osmotic regulator(s). The lime water is then released into the aquarium in small quantities in regular intervals. The calcium dispenser is fitted between the metering pump and the infeed hose. All TUNZE® Osmolator, Osmomat and osmotic regulator sets can be used. The calcium dispenser can also be installed in every water storage tank. The dispenser tank should be topped up with calcium hydroxide every one to two weeks.
The calcium dispenser and the calcium reactor can be combined well with each other. An especially well set pH stability is achieved during the day as well as at night. An increase in performance can be achieved for a larger consumption.
