The wavemaker is not available yet and probably won't be for months. It is interesting to see the fish surging forward every time the wave goes their way. I am not sure how this would work with the typical reef-ready tank, since it looks like some room is needed at the top to contain the sloshing of the water. The water level in most tanks is pretty much fixed by the level of the overflows. I guess you could cut away the top of the overflow to lower the water level. I had a surge device at one time (Does anyone remember the Silent Surge) and it created some water management problems in my tank. It looks like this might create some of the same sorts of problems.

I can email you the 1 MB movie file if you want. Just send me a PM. If it's the PDF you can't see you might need Adobe Acrobat reader. Here's the relevant text:

Wavebox 6212 – near-nature water movement
TUNZE® Wavebox 6212 is a wave generator for aquariums from 200 to 1,200 litres (52 to 317
US gal.). It is especially suitable for reef biotopes as it generates an oscillating current. The
current corresponds exactly to the wave structure and water movement in reef top zones. The
Wavebox applies this oscillating principle through
Wave Controller 6091, which uses the intrinsic
resonance of the tank. A very low power consumption
generates ideal water movement. The
water is in movement in all areas of the aquarium,
even the smallest section behind a decoration
benefits from the wash.
Example: On account of the wash of the waves,
the maximum water level may rise 2 cm (.78 in.)
and more in aquariums with a length of 1.5
metres (59 in.) The wave height can be adjusted
electronically.
- Oscillating current with near-nature wave movement
and circulation
- De-sedimentation of the entire aquarium habitat;
natural water movement for fish and corals
is produced
- Wave generation at low power consumption
- Supplements existing circulation pumps
- Little space required
- Dimensions: L 125 mm x W 113 mm x H 300 mm
(L 4.9 in. x W 4.4 in. x H 11.8 in.)
- For tanks from 200 to 1,200 litres (52 to 317 US gal.)
- For larger tanks, an additional Wavebox extension
(without Wave Controller) can be used to
extend the system
Wavebox 6212 EUR 383,77

Fine sand

The prices are recommended retail prices without VAT
De-sedimentation in
stone structure
The pump in the Wavebox presses the water to
the left-hand side of the tank causing all polyps in every position in the tank to move to the left.
The pump is stopped; the Wavebox fills up; and
the entire water in the aquarium returns to the
right-hand side. All polyps move to the right.

It' looks a like a very cool wavemaker, ditto what Dougc said though about the water level...

BTW 383 Euros = approx 460 US$.

That is an absolutely humungous amount of water movement! 8O

The wave frequency would depend on the length of your tank. You'd have to tell the controller the approximate inside length of the tank and then you'd probably be able to tune the wavemaker a little bit either way to get the most efficient water movement.

I'd think that this would definitely limit your tank to shallow water inhabitants. Deeper dwelling fish, used to more stable conditions would probably completely flip out, but anything that lives near the surf zone and is typically exposed ought to adapt just fine.

As others have mentioned, tanks with corner overflows would have a few more things to worry about, though tanks with center overflows should be completely unaffected.

Oohhh. I want, I want...

>...De-sedimentation of the entire aquarium habitat;

Sounds like a bad idea if you have fine aragonite sand....

>...The wave frequency would depend on the length of your tank.

Well, it is a good approxmation, but not very exact.

Nevermind about my comment about fine sand.

Actually the flow is not that much, but the fact that the slow oscillation make it appear that way. It is better use of energy to rock the water up and down with the resonance of the tank, and some public aquarium use hydralic actuator to accomplish the same thing.

Oh, make sure the tank is quality one.... the resonance of the water can really burst your tank if it is poorly made, ...I am sure the motors in these are not that big, but you have to be aware of it. I am sure some tank manufacturer will say the warrenty is invalided if you use one of these guys. :D

Can't you achieve the same effect by living in an earthquake zone :roll:

>..I'd like to see the innards of that box.

Just an empty box with a pump specially designed to push water out.

Try this at home. Fill an empty milk jug up with water, and hold it with your hand. Now, pushing it in and out of the water, until it is in sync with the wave it's making. That's it.

I'm specifically interested in seeing what the pump looks like and how they can turn it on and off every second without causing the motor to burn out. You have to move a lot of water to displace the volume in that box every second. I'm wondering if they're using a propellor-style pump or what exactly. I'm guessing they have a tunze stream in a completely sealed box and just cycle it on and off really fast but I'd like to see just to make sure. :P

Once the wavemaker is in resonance with the wave, it will take little energy to restart. Everyone really need to do the milk jug "experiment" to appreciate how easy it is to rock the water like that....

As to the pump, a propeller-type like the Stream will work. Again, there is not that much flow that you need to get the top-of-the-line Stream to achieve that.

I would imagine it works like the turbelle electronic pumps which are low voltage and don't really turn off and on, but speed up and slow down via an electronic control box. Cycling an electronic pump on and off will quickly destroy it.

Looks awesome, but I would live in fear of it rupturing the tank. 125 gal of water sloshing back and forth is a LOT of oomph. Maybe if I ever go back to an acrylic tank.

I really love tunze equipment. Just wish I could afford it! The wavemaker specs out at roughly E384. That's what, just over $400 american? Maybe $420? Hefty change.
