I thought those things were supposed to be near silent, that sounds so horrid!

That sound was his fans that cool his halides.

I don't like it. It's a seiche, not a passing wave. And the motion is just annoying.

Looks kinda scary up topside.

HOLY SHNIKIES!!!!!!!!!! That is some serious action. WOW.

I think it would be better on a longer tank, like 125/150/180.

Is the tank in an earth quake zone?

 

[Anonymous]

Seems also to me that it moves to fast. Dial it down maybe to a realistic action. I don't think I would ever put on on my tank just because of the top side action. Screams shattered lights and water spills.

Seiche is common when earthquake happens. Some of my coworkers who were here back in the 1994 Northridge earthquake says that their pool overflowed. Probably was not fun if they were in the pool at that time.

1989 Loma prieta quake here my toilet sloshed around and spilled water out.

I've seen one in action. It's a very interesting effect. I'd only use one if I could design a custom tank that had several inches of extra space above the static water line. Also, the fast ebb-and-flow does get a little naseuating to stare at.

You can't, it works on the resonance frequency of the tank, which is set by the length of the tank. You could probably up the frequency and get more than one node in the standing wave...

Don't you all think that that would eventually wear on the tank's silicone joints and eventually break one of the sides away? That looks a little too wild for me and I wouldn't trust it. I'm sure that wouldn't be good on a skimpy tank stand either.

You can dial it down. In the thread the guy says it is on 100% and he usually runs it on 30%.

Not familiar with the controller (Tunze 6091), but there are two ways to make it less powerful. You can either detune it out of the phase, so that it does not resonate with the tank. Or you can make the pump weaker. To be useful, the controller must be able to controll both the frequence and the power to the pump.

 

[Len]

You can adjust the speed of the pump which should adjust the frequency (unless I'm using the the terminology incorrectly). The wavebox is a pump (i believe it's a Tunze Stream) housed inside a box. I believe as the box fills, it creates a surge. Having the pump at full speed means it surges more frequently. Having it at lower speeds probably means it surges less frequently but at the same intensity.

 

[Len]

Hmmm. The Tunze literature says the wave height can be adjusted "electronically," so maybe intensity can be adjusted too.

 

[Anonymous]

The frequency I mentioned above is how often the box change flow direction (or turn on/off). It is not how many Hz it is driving the pump for if it is a variable pump (like PWM type of control).

 

[Len]

Then we're talking about the same term. From what I saw, you control how often the box discharges/changes flow by adjusting the pump speed.
