Tunze decided to release retail MSRP pricing for the new stream 2 pumps. These pumps are the next generation pumps destined to replace the older legacy stream pumps. We already reported on prices for the 3 Tunze stream 2 pumps that aren’t controllable. However that leaves 3 more pumps that are controllable, the 6105 (3,434 GPH)Â is coming in at $370, the 6205 (5,811GPH) is hitting at $590 and the beast that is the 6305 (7,925 GPH) is landing at $840 a pop. Tunze has a potential hit on their hands, with the improved features included built in magnet holder and faster GPH times. If you opt for the Tunze Turbelle Stream 2 6305 in your aquarium, hook us up with a video of the flow. That brings a new definition to the word “flowlicious”.
