Co2 Tubing question

Does anyone who sells co2 tubing thats of decent quality? I saw AQUATEK CO2-Proof Tubing on amazon for a decent price but there is no reference on quality

Thanks

I'm not sure if AQUATEK is the greatest quality - Normally they offer things for a cut price for a reason. I'd say if you want a sort've "quarenteed" high quality CO2 tubing, go get some from Green Leaf Aquariums (GLA).

Is there any particular reason you want CO2 tubing?

I have used regular airline tubing and silicone tubing (which are generally cheaper than CO2 tubing) with no problems.

it's not hard to find info on how "regular" tubing has pores that will allow co2 seepage. on paper I suppose that's correct, but for our purposes and low pressures, I really don't think it worth the effort or cost. use what ya got.

I have read this as well once before. Air line tubing allows gases to pass thru its membrane at a higher rate than specific co2 tubing. Most will reach the end but some does escape thru vinyl tubing.

As mentioned, theoretically, yes, regular airline tubing has a higher permeability rate than CO2 specific tubing, but for our intents and purposes, it does not matter.

There was a Cole Pharmer specification sheet that outlined the permeabilities of various materials to CO2 gas, and I believe silicone tubing was the worst, but still a negligible rate (10 to the -3 or -4 order or so).

Co2 Tubing question

Green leaf aquarium has some decent co2 tubing. But the best one I use so far was clippard tubing. I just can't remember who here sells it.

I think standard tubing will be fine. I personally use tygon R3603 just cause its pretty strong, but i suspect that airling tubing would suffice.
