Tunze 9001 Skimmer question

[jesspal]

The tubing for the silencer/airscrew seems short. In a lot of videos it looks like people are able to lengthen it enough that it hangs over the back of their bank. How can I open the larger plastic tube and adjust the airline so it is longer?

I'm looking at mine for my 20gal right now, you can replace the tube with longer tubing. it plugs into the skimmer down through the bubble chamber into the pump. is that what your referring to?

I wouldn't even use the air adjustment. They work better wide open. The water moves through the body faster when you reduce the air which can lead to more bubbles being discharged from the bottom of the skimmer.

Maybe it’s the silencer I’m referring to, it’s only like 4” which leaves it floating in the water.

Oh, I see, I would just buy some silicone tubing to lengthen it a bit then. Only use what you need though as too long will reduce air intake.

The tubing inside diameter is the same as any standard airline, so you can just swap the airline, the longer you make it though the more you will restrict the air flow, I generally would try to keep it as short as practical. We use a thicker walled heavy duty silicon tubing, we sell it in a roughly 16ft roll as a tubing for airline, part 7072.200

that's what I did. replaced the hose I actually removed the silencer and ran the tubing out the window to help with pH swings I was having with this setup at the time.

 

[jesspal]

Thanks everyone. I’ll just buy a bit of tubing and let it rip.

The instructions say not to lengthen the tubing?

You can within reason, needlewheel pumps do not have a very strong suction for air, as a result lengthening the hose restricts air flow, if you add a few inches, maybe a foot, the difference is negligible, but you can;t add multiple feet without seriously impeding performance.
