Reef Octopus Classic INT 8" - Air Silencer

Last night when I was taking the skimmer apart to clean it, I accidentally dropped the air silencer to the ground, and just like that, it's in pieces.

After doing some research, they are running $25 brand new

That had nothing to do with this thread, but little run down on why I'm questioning the silencer to begin with......But, in the silencer chamber, there are two tubes. My silencer has one port coming in to the bottom of it, and two coming out the top. Both of them exit through the top. One tube is open, and the second tube has a black cap which closes it off. What purpose does the tube that is capped off serve? Why have it there at all.

Here is a link to the silencer. You'll see the two different options.

Google (Jeremy from coralvue says)

Quote:
The black caps are used to direct the air flow through one tube which allows the silencer to well, silence the vaccum sound. If the sound from the silencer does not bother you without the cap I would suggest not using it as it does restrict the air to the pump slightly.
So it seems that one tube can be a restriction on some units and they have a second tube to reduce backpressure,etc... leaving the cap off is preferred by some extra noise reduction (and potential performance loss) can be seen by using the cap..
