    Now this is what i am talking about!
    I hope all companies learn from this and provide feedback on their pumps/equipment once they have dissected the results for themselves and can provide an adequate response



    awesome stuff Tunze

    What an awesome video just saw it now, Go Tunze!
    Now if only you had not put your foot in your mouth the 1st time

    lol maybe they made this one just for the video. They should have done this when the whole thing started

    very imformative vid on flow around a reef (and pretty little sohal tang too), enjoyable to watch :)

    I think someone must test their own one.. Anyone up for it?

    its titled Tunze video response challenges the conclusions, not the data, of the propeller pump study.. lol

    Tunze and Ecotech can put up a million vidz...
    As long as they are making proper progress and changes - we benefit!!
    and thats the important part..

    This is the email I received from Germany, I will not add the German one as the literal transalation when put on was a laugh and this is a serious matter

    Comment regarding the article by Michael Sandford, William Straka, Sanjay Joshi, regarding "… flow output of aquarium propeller pumps"
    The published article on flow measurements at EcoTech USA shows that obviously the pumps of this company have good results. The fact that a competitor was involved in the study makes it possible that method was selected in order to achieve an economic benefit. The measuring constellation and the correct consideration of turbulences appear, however, not to be fully processed. The measured pumps of competitors have no flow correction to reduce turbulences, like our pumps. They measured turbulences and thought it is pump volume. We have since done further testing that clearly shows our flow is superior and a video of these tests is online now. To measure these pumps is not possible without having measuring failures, by reason of the turbulences and low pressures. The flow rating is therefore based on theoretical values and is for comparative purposes to equivalent powerheads.
    Since inventing this pump class in Jan 2002 and unveiling it to the world at Interzoo May 2002, we have been copied many times. We put into question, however, that this measurement is the only evidence of how suitable a pump is for an aquarium. Due to the construction of our pumps, it is generally proven; we have stronger, directional design for flow across the aquarium reef than other manufacturers. The design of our pumps allows a much better flow. Our construction gives the flow a direction and therefore it reaches further than the pumps of our competitors. We have detected that the flow of their pumps have such a short reach due to a flow short-circuit, caused by turbulences. Our pumps have a better coverage and no lower width of the flow. This important practical result has also not been taken into account.

    Video to this topic:


    I have not joined in with the wrangle so far due to various reasons, but the integrity of TUNZE should be commended, as no slating of the oposition was made what so ever, even though the other pump was made to look superior for economic gain. Whatever the results I'm sure the lessons learnt here from both companies will help to improve the equipment offered to aquarists in the future. Which means our opposition will still be copying TUNZE innovations...........:whistling:

    So what they are trying to say is that even though the pumps dont actually push out the advertised liters (eg 5000L), they are equal to a pump that pushes out 5000L because it just works better/economical?

    I believe that both (Tunze and Vortech) are excellent pumps, and the fight will continue... it is not necessarily a bad thing, it will lead to improvements on both sides! We see it everywhere, think about Audi, BMW and MERC, who builds the best car...

    Tremayn i think tunze is saying there is a difference between flow and turbulence. tunze says their pumps make a circular flow ring in the entire aquarium. This is visible in the vids as the tunze pumps make a jet of dye across the entire aquarium. If you look at the dye spread of the competitors pump they barely make it half way. The test ecomarine did was at the point of exit from the pump. These test although there are no numbers, visually we can see the tunze provided more flow through out the entire tank. Thats at least my conclusion from this video.

    At Last someone who understands the difference between turbulence and flow, thank you for that short to the point analysis Steven:thumbup:

    @butcherman they did use an MP60 check out the flow ratiings of the pumps when they use them
