Loud Skimmer

[Chowder]

Hey my Skimmers air intake is quite loud. I was wondering if anyone here has any ideas on making it quieter. Here is a shot of how it is set up now. The air line is set into the collection cup to draw air and the other side is connected to the pump.



I was going to try and take the line out from the collection cup and just extend the line so it's 10x or more longer to cut down on the noise. Any other ideas would be greatly appreciated.

Thanks, Chris
