Tunze’s Next Move

 In the wake of the article, Experimental Comparison of Measured Flow Output of Aquarium Propeller Pumps, a lot of Tunze owners and curious onlookers were left wondering what their next move would be. Due to the fact they were shown the article before it was published, Tunze was not caught unaware and quickly put out a press release in which they described the methods which got them their flow numbers as well as some plans for the future. To be quick, it left me less than satisfied and wanting some more details about what was going to come next. A conversation with Roger Vitko of Tunze after the jump… I managed to get some quick information from Roger Vitko of Tunze today, and it’s finally what I’ve been hoping to hear. As Roger put it, “there is no conclusion to be drawn as of yet. We only acknowledge that doing the same test, the same way, we get the same result, but we have a lot more to look into.” He also tells me that they have been working hard on this since the article came out and that “A comprehensive comparison of the pumps will be done, we will test everything, not just flow at the pump, but flow where it matters at the corals, at your reef. We will test decibels, flow pattern, flow at distance, you name it.” Roger simply asks that we give them a chance to figure this out before assuming anything, and I would like to ask the same. Everywhere I look people rant about how we assumed the pumps were tested well before and we should not do so again, but then aren’t we doing the same by jumping on the heals of this new method a little prematurely? We need to give time for some rebuttal before we call this one fact. Roger also gave me some details about results they have already achieved and how they are looking to get to where they want to be. “In addition we will work on increasing the flow at the pump, we have already accomplished 3200gph from a 6105 and 4900 from a 6205, 6305 will require new parts be made and tested but they are already being designed and when I arrive 3D prints should be ready for testing. Of course getting from that to a molded part takes further time. We will test these solutions for noise, flow, power consumption, etc, before we send them out. ” I think it should be pretty clear that they are not trying to duck anything, so lets give them a chance to further our knowledge still about fluid dynamics in the reef tank. Lets not count one of the primo manufacturers in the industry out quite yet.
