Splash! Splash!

Roger:

For years now I've fiddled with the standpipes in my overflow boxes presuming they are the source of the noise in my tank-with-wavebox. Took me that long to figure out it is the wavebox itself.

On each pulse, when the water level lowers on the side of the wavebox (and thus filling the wavebox) there is a splashing noise that is audible more than I would like in my living room. I am assuming the splashing noise is the box itself filling up.

I may still be wrong but I think this is it. It is certainly happening on each pulse when the water level lowers on the side of the tank where the wavebox is mounted.

Is there a cure?

Thanks,
Joel

People normally describes the wavebox as sounding like Darth Vader..

I have the underlying Darth sound too.

I have never had a splash noise come from a wavebox itself, usually the only noise is the "Darth Vader" breathing noise as it takes in air.

 

[ostrow]

Um, well, should I call? Or, you want to call to hear it?

I won't be able to determine that it is coming from the wavebox, anytime you have a wave or a surge in a tank some splashing is innevitable but the source would more likely be the wave hitting the tank walls or the overflow box. I don't see how the splash noise would come from the box itself.

I think my favorite Tunze Rep had a bit too much egg nog over the holidays. OR maybe it was champagne!

So, I opened up the top of the wavebox (after cleaning my overflow box ... grrrr!) and guess what? The splash is in there.

I've seen various and sundry reference here to two holes in the back of the wavebox.

What are those for?

What is the drawback of closing them?

What is the best method of closing them?

Splash, splash.....

They should be closed, the screws that come with the mounting rails should be installed but I have never known this to make a splash sound. I will send two screws but the influx of water should not be enough to make much noise.

It makes a HUGE difference when I plug them with my fingers. The water drops a good 2-3" below the holes. Water streams in there and echoes I guess inside the box. It is like a faucet turning on and off full blast every second or so.

 

[rvitko]

That is probably why I have not experienced this. My home aquariums have always been 4ft so they water level just barely drops below the screws at the proper pulse frequency and I could see the influx of water but it was never audible.

Ahhh, quiet.

Thanks Roger!
