I recently purchased a new Tunze Streams 6101 pump to replace a 6100 that developed controller issues. I thought people in the club might be interested in "whats new" with the 6101, so here goes...
Whats in the box?
Package contents are (in left-right, top-bottom order):
Mounting hardware kit
Streams Pump with integral controller module
Instruction manual (in several languages)
Snail guard screen

The power supply has been upgraded to a switching type as opposed to the transformer included with the 6100. Look closely at the bottom of the power supply and you can see the small, clear jumber that you swap with the one in the plastic bag to reduce the output of the pump to the 6000 level.

In this closeup, you can see the "speed control box". The small black box at the end of the cord replaces the large blue aluminum box on the 6100. You can see the small, white speed adjustment knob just above the DIN connector for the cable that will run to your controller.

From this picture, you can see that the pump bodies look the same from the outside.

The impeller on the 6101 is slightly different than the original 6100 impeller. The original Streams Impeller has a type of brake assembly that has been removed on the 6101 unit. In fact, if you need to order a replacement impeller for your existing 6000 or 6100, you will get this newly designed impeller assembly. It looks to be much simpler and doesn't seem to affect the pumps performance.

Thanks for the review. I didn't realize they were DC powered.

In this picture you can see both complete pumps, side by side.

I don't see or hear much of a difference in performance between the 6100 and 6101. Both pumps seem to have similar output and are totally silent in my system. By switching a jumper on the power supply, the user can choose between high 36 Watts (24V) 1056-3170GPH or low output 18 Watts (15V) 660-1849GPH.
Both come with the same, useless mounting hardware. All the mounting points on the 6101 pump body are the same as the 6100. If you have a typical glass aquarium with a plastic frame around the top, do yourself a favor and get a magnet mount. The included mounting hardware is useless for this type of aquarium, however it may work OK for acrylic aquariums, I do not know...
The power supply and speed controller box is much more modern than the orginal. However, I wasn't impressed with having to use jumpers to switch between high and low output. For the money, couldn't they have put a switch somewhere rather than providing 2 different jumpers. I fully expect not to be able to find the other jumper if I ever want to change the output levels in the future. Also no convienent mounting method is provided whereas the original transformer could be mounted with a drywall screw and the old speed controller box mounted with a couple small screws. I resorted to zip-tying the cords to screws driven in the wall to hold the power supply box to the wall.
The owners manual mentions a "Turbelle safety connector 6105.50" that will automatically switch between wall power and a standard 12V battery (or 2 batteries in series) to automatically power these pumps through a power failure. If you need protection from extended power failures, this could be a great solution since you could get extended run times (days) from a small car battery or 2...
Overall, the 6101 seems like a logical evolution of the original.
Very cool. Definately looks less chunky and like you put it, evolved.

Awesome write-up Jon! Thanks!!!
