tunze wavebox in action

however what concerns me is the tides effect on the overflow because that tank doesn't seem to have an overflow,
I am not quite sure but I think that I see tunze overflow in the midlle of the tank.
Sorry blues...didn't realize you had already posted.
No problem at all:) ,we are here to share informations.
 
Beerguy- as for the tangs you should know Axel Tunze pioneered a belief that agression only results from competition for food and sex- same as for humans and so if you feed sufficiently no problems arrise- that is also a 7ft aquarium and the fish are very well fed. The overflow was no problem- in the center is a hnag on overflow- now, it may be noisy on a US splashbox but with a durso that should be solved. I need to study this further for the US market. You can control wave height and frequency so you could have two small waves instead of one big one if you choose.
 
Thanks Roger! I'd be very curious how a US style overflow deals with this. And if you need a beta-tester for an 8' tank, I'm willing!! :evilgrin:
 
The problem now is we only have two and with no manual they are not at all user friendly, it is not a device for the novice so I don't want to mislead anyone as it requires a fair background in physics and aquarium keeping as well as containing several components that have to be set up just right to work. It isn't beyond a reef keeper with at least moderate experience but it is more complicated than the electronic streams and multicontroller. You can imagine that it took over 2 years to get from a strange vision Norbert Tunze had from visiting a wave pool, to one Claude Hug refined using some fundamental prinicipals of resonance. Then Norbert, Axel and Claude worked for many months to resolve all sorts of detail problems like noise, bubbles and trying to make it as user friendly as possible. As impressive as that video is, in person you will not believe it. 9 out of 10 people looked for some other device and you just cannot really see the water movement from the box- it isn't at all like the Stream it is based on. I will have it at IMAC in use. For the bad news I will not attend MACNA as we have too much work to do and I am going back to Germany in September to work for the new catalogue, manual revisions and the new inovations for 2006 :)
 
Hey Bob - I just noticed Columbus IN. in your Avatar.

What a coincidence - both my daughters live in the area. You still practicing medicine in Columbus?
 
Roger,

What kind of impact would the wave action have on the lateral stability of a tank stand over a period of time? I am thinking the longer the tank the great the impact, or at least some good wear and tear on the corner joints maybe.

I am in the process of designing the stand for my first tank, 120 AGA, and I am wanting it to be nearly bombproof, so the stability thing immediately came to mind while watching the video.

It seems really incredible. I will be watching for this as I gain more experience in this addiction, ah I mean hobby :)

This is a very novel idea. I'm sure you have to program or adjust the cycle frequency to match the resonance frequency of the tank water. And to get 2 waves you just double that input frequency. This has got to be a big unit, basically I am thinking this is just a large bore short stroke piston moving a large volume of water over a large output area. Inteasting.

I am curious to see how this will work with various types of rockwork and tank sizes. Seems like some tanks would be more prone to this wave action, and some would be extremely resistant to this type of motion.
 
that type of wave motion, imo, is the most realistic wavemaker i've seen yet. Any divers out there ever dove in a bit of rough water??...It is EXACTLY like that. A strong, back and forth motion. Great comments on the stand being able to take it. I love it.
 
I would also be worried about tank stress with that much water movement. Columbus, IN, is a weird town. I've been there a bunch of times and it never seemed quite right. Kind of reminded me of the TV show Eerie Indiana. Everytime we were there it was a weekday, and no one seemed to be working. Everyone was just kind of out and milling around or jogging. The buildings are great though, and I love the Cummins Diesel building.
 
I think a tank would have to be made out of card board to fold from a 1" wave. The longer the tank the more noticable the wave- the video is of a 7ft (2m) aquarium. The box is a standard Comline box about 4.5" square and 11" tall. There is one moving part - the Stream propeller. It will work on any straight tank of at least 2ft long.
 
Roger the bad news is that most of us can not attend the I Mac show could you show a pic of the tunze wavebox? would buy if i could see one. RGibson
