Well, that's a huge loss... I'm I still doing something wrong?
equation, wrong assumptions?
Some wrong assumptions I think. The CO2 pressure differential in the
silicone line is less than 1 psi in low-pressure systems. I have my
three-tank manifold regulated at 2 psi with bubble counters at the
manifold. One silicone tubing run length is about 15 feet and is
introduced at the input of an Eheim canister filter where I can see the
CO2 bubble through the tubing. I see the same bubble rate at both ends.
Presumable there is some CO2:O2:N exchange across the wall of the tubing
but it is EXTREMELY negligible at the very low pressure differential.
If spending a buck a foot for special tubing makes you feel better about
your system though it is really a small price to pay. If you want to
get really high tech you should check out stainless steel tubing.
