Tunze Turbelle Stream 6100 Unit

This is a very powerful water pump called a Turbelle Stream model 6100 sold by Tunze. I use two of these pumps in the display tank.

This model processes 3175 gallons per hour while only drawing 45 watts of power.

Looking at the picture to the left, going clock wise the power head itself is in the upper right corner. The blue box below is is the driver housing. The lower left shows the box it ships in, just above that is the transformer that powers the driver box.

Tunze Turbelle Stream 6100 Power Head

This shows a close up of the power head unit itself.

As far as power heads go this is a rather large unit at about 4½ x 3½ x 3½ inches. It could even be called ugly. There really is not an easy way to hide it either.

However, the high volume of water it can move, the flexibility in its programming and the very low power draw make it worth it.

Tunze Turbelle Stream 6100 Impeller

This is the impeller of the Tunze 6100 unit. The protective covering comes right off making it easy to clean.

The impeller sides right out for cleaning or replacement.

Tunze Turbelle Stream 7094 Multi-Controller

This is an advanced Tunze multi controller which is able to directly program 4 stream power head units. With the use of a Y-cable it can be used to control 8 steam units.

The controller comes with a photo-electric cell to detect lights out and will reduce flow patterns while the lights remain off.

The unit has a food timer button (red) for short term reduced flow patterns while feeding the aquarium.

Tunze Turbelle Stream 7094 Multi-Controller Programmed

This shows the 7094 as I have it programmed to power two 6100 Turbelle Stream pumps.

A three second interval between cycles starts the process. Pump 1 (Channel 1, port 1) starts at 30% power and slowly ramps upto 100% speed randomly between 1-7 minutes. Then the pump turns off. Pump 2 (Channel 2, port 2) starts at 30% and then slowly ramps upto 100% over a random 1-7 minutes.

This provides a nice long cycle wave action.
