Post Slimy CO2 tubing

Every time I pull out the vinyl tubing from the DIY yeast setup, the part that was under water always has a very slimy texture. I assure you it isn't algae. The most weird part is after touching the slime and rubbing your fingers together, there nothing there. No slime actually comes off and it seems that the tubing actually changed texture. .

Just wondering if anyone else has had the same experience. To narrow down what is causing the slime, PLEASE post:

a) Weather it is a DIY yeast or pressurized setup.
b) The material of the tubing.

I'd be inclined to say it's the deterioration of the tubing. Mine also changes color (from blue to green) and STINKS a lot.

I just replaced my tubing three days ago and it has been as slimy as all my other ones. Unless it is deteriorating that fast, I just don't know. The tubing is clear to start with then goes to opaque white.

I do get it as well...
But I'm not too sure what it is either, to tell you the truth.

chic - so is it on the DIY yeast setups or pressurized? What is the tubing made of?

Well, I don't smell mine but none of them change color. I use blue silicone tubing. I know it's not the best choice for CO2 injection but I have never noticed anything bad using it.

DIY, and it's the silicone tubing.

If I had to guess

I'd guess the CO2 had made the water that periodically enters the tube acidic, probably somehow changing the chemical characteristics of the plastic.... making the clear tube milky white and slimy.

Just a guess.

I've had this problem with vinyl tubing with any part of it below the waterline.

To be honest I've never had the problem with silicone tubing.

But then again, the silicone tubing I use is already cloudy and blue.

i notice the slimey-ness on my silicone tubes too

perhaps its just how silicone is underwater...?? what i do notice though is that a lot of snails slide on the tube and such, maybe..its like a product of the snails? although of course if your tank had no snails that wouldn't be the case
