Since I'm new to this site I thought I would test out the blogging feature by copying a short one I did on my site :). As some of you may know a couple of of weeks ago a group of aquarium gurus published a study measuring the flow of propeller type pumps. During their testing they published some dissapointing flow results for the Tunze pumps. Tunze has now come out with their own responce video:
Instead of trying to argue against the results of the study it appears that their argument is more aimed towards saying the type of flow that the tunze pumps produce is better. If you have a chance to watch the video I'd be interested to hear your opinions.
