Neele Wheel Skimmer Air Intake Noise

[werkkrew]

I have done a few searches and come back with nothing.

I am running a Coralife Super Skimmer, and much like all of the other Needle Wheel skimmers it has an air intake hose with a canister silencer on it.

The rest of my system is dead silent, no noise from pumps or powerheads, but I hear this hissing sound coming from my air intake all day and its driving me nuts.

If I put my finger over the hose all the noise goes away.

Are there any mods or any other way to quiet this thing down? Im sure someone else has figured this out.

I researched this some months ago as my Euroreef was noisy and came with no silencer at all. What I did:

I drilled a hole in the bottom of a plastic pill bottle through which the intake hose is inserted. The lid has two holes with short pieces of tube inserted (you can use one). Mine looks like a miniature automotive dual exhaust muffler. Anyway, I put in a piece of porus sponge material and a cotton ball on top. Some use charcoal in place of the sponge. ( be sure to keep whatever from plugging the intake holes) You could probably use a variety of things. Anyway, the noise is gone.

Exactly what I did minus the carbon.

I did a very similiar job with a small tupperware container. I used three tubes on the intake side (the goal being to reduce air flow or velocity through any single inlet). I used filter floss as a filter. Definately decreases the noise coming from the air intake.
