Tunze Aquarientechnik GMBH Investigated by Washington, DC-based Law Firm

Posted on Friday, August 26th, 2011 at 10:02 am by

In a recent press release, The Lewis Firm PLLC announced it’s investigation of Tunze for misrepresentations regarding the output flow rates produced by some of their propeller-based circulation pumps. Now, let’s say right off the bat, that a pending investigation means nothing, and is not by any means proof of any wrongdoing. The question, we believe, will focus around how flow is defined and therefore measured. A recent study at the Penn State University found that Tunze “allegedly” exaggerated the flow rates of the Tunze 6105, 6250 and 6305 series pumps by 46%, 80%, 120%, respectively. Again, an allegation means nothing, legally or ethically, but it will be interesting to see how this investigation is conducted.

Here is the official Press Release found on

WASHINGTON, Aug 25, 2011 (BUSINESS WIRE) — The Lewis Firm PLLC is conducting an investigation into potential violations of consumer protection and false advertising laws by Tunze Aquarientechnik GMBH, a Penzberg, Germany-based manufacturer of aquarium components, and its North American subsidiary, Tunze USA LLC (collectively, “Tunze”).

Specifically, the study found that the stated flow rates of Tunze’s 6105, 6205 and 6305 series pumps are exaggerated by 46%, 80% and 120%, respectively. (See By contrast, Tunze’s competitors were found to have either understated or accurately reported the flow rates of their propeller pumps. (See
