Tunze nano or Koralia 4?
- Thread starter sgarron
- Start date
or you could wait until fall - when the 6105's come out and all the tunze fanatics dump their existing tunzes for the new ones. You know there are always the folks who want the latest and greatest...(you know who you are if you're reading!). 
From Tunze:
Eco-energetic
The innovative motor based on the eco-energetic concept and the newly developed
pump technique ensures a very high efficiency at very low maintenance and power
consumption.
Very silent run
Special plastic bearings, a titanium-alloy axle and silicone absorbers enable a very silent
run without wear which applies for smaller models as well as for the powerful pump
delivering 30,000 l/h. (7,925 USgal./h).
Large suction area
The water which is drawn in passed through a giant intake strainer, and thus prevents
premature soiling.
Magnet Holder - a standard feature
As a standard feature, Turbelle® stream® is supplied with a magnetic holder, which
enables uncomplicated attachment at any position on the aquarium pane from 19 mm (.74
in.) to 25 mm (.98 in.).
Flexible adaptation
The ball-type design is an intelligent solution for installation with a minimum of hydraulic losses. Contrary to other pumps, they offer a lot of
flexibility with respect to positioning and orientation of the water beam, which can be adjusted in such a way that an effective flow is produced
over a long distance in the aquarium at lower power consumption.
Controllable output
The Turbelle® stream 6105, 6205 and 6305 pumps have been fitted with electronic speed controllers running on safety extra-low voltage.
They are ideal for wave or tide simulation in every aquarium, and contain a new „intelligent“ micro-processor controlled motor. Along with
Multicontroller 7095, 7096 or Singlecontroller 7091 they are an unbeatable team.
No problem in case of power failure
Fitted with Safety Connector 6105.50, Turbelle® stream 6105, 6205 and 6305 can be operated on every 10 V to 24 V direct-current source
(battery, solar cell). The safety connector permits normal operation with the TUNZE® power supply unit, but in case of a power failure it will
automatically switch over to a car battery or a direct-current source.

i have both Tunze 6045 and Koralia 4 u are right about the flow pattern, i got the tunze for my 50 gallon & it works great, i use the koralia4 for my 75 gallon just to help with water movement & the first thing i notice was a different water pattern, IME i like the tunze better because it is smaller, they both work great.
