Adjusting size of wave from wavebox?

[funnyguyMI]

I am setting up a 180 and had it nearly full of water and put my wavebox in. Adjusted the frequency to get the resonant frequency of my tank and had a nice wave going.

I finally got my plumbing leaks fixed and started running my return pump, and now my water level is up about 3/4" from where it used to be. Now, the wave is too tall and splashing against the top bracing in my acrylic tank.

Can I adjust the size of the wave? If so, would I do that by altering the frequency on the control panel, or the little screw in the controller?


Thanks,

I've got a tunze wavebox on my 180 also. It splashes against the top acrylic just like yours. The only thing that I can think of is to lower some of the slits in your overflow to lower the water level in the tank. Adjusting the dial on the wavebox either way will only decrease the wavesize. It seems that once you find that "sweetspot" or resonant frequencyfor your tank on the dial, it is still generating a large wave, but just happens to be slamming against your top acrylic.

You adjust the power of the pump using the potentiometer on the driver or junction block.

I thought that maybe you were trying to keep the large wave, but just not have it splashing against the top. If a smaller wave is what you are after, RVITKO is right. You can simply adjust the small screw on the driver to reduce the output power to the pump in the wavebox. You may have to readjust the cycling frequency to find a new resonant frequency though with the reduced power, but I'm not 100 percent sure. It seems that when I was messing around trying to get mine dialed in, if I adjusted the power, I also had to adjust the frequency.
