One thing that has really been annoying me over the last few weeks, is the horrendous noise the skimmer makes. The unit in question is the TMC v2 Skim 120 (http://85.133.58.150/Catalog/Product/24)
After a bit of playing around, I found the source of the noise is the air inlet on the unit. So time to get the Dremel out….
First step, is to split the unit as per the manufacturers instructions,
Here are some pictures of the bit we will be removing :
Now time to get the dremel and drill out…
First remove the top of the air intake :
Now I removed the blue air-intake and removed this bit
I had a bit of spare 6mm air tubing with a silencer on the end
So i drilled the hole that was left, out to 6mm
Now time to re-assemble…
First remove the blue pipe completely from the mixing head, and push your new hose onto this
Now re-assemble as per manufacturers instructions..
The skimmer re-assembled
Silence 🙂

Hello Adam,
I was delighted when I stumbled across your video on youtube last night. This led me to attempt having a go at silencing my TMC V2 200 Protein Skimmer. I have removed the piping, drilled the holes and fitted the pipe… However… I am having problems finding a “silencer”?!? Could you please give me some more information as to what you used and where you got it from?
Thank you for your help

Hi Blimburn,
The easiest and cheapest option an ordinary airstone which you should be able to pick one up from your local pet shop.

Hello Adam,
Thank you for the prompt reply. I had actually tried the airstone method today to no avail. I have done lots of hunting and I think I have finally found out what it is called… A venturi value?
Please advise me further
Thanks in advance

Hi Blim,
Have you tried a syringe, take the plunger out and put a a bit of cotton wool in the tube then attach this to the air intake.
this is also similar to what I was using : http://www.amazon.com/Coralife-Replacement-Super-Skimmer-Silencer/dp/B008G0CDR4

Hi Adam, Followed your instructions and it worked brilliantly! After a year and a half of putting up with that damned squelching noise, just a quick? ten minute job and it’s sorted. Yippeeeee! Peace and quiet! Thanks for taking the time to help others
Cheers
