co2 tank resistance

**plant talk** · 29th Dec 2002, 00:18

Hi,

If the air tube is more than 10m long becos the co2 tanks is left in the kitchen but the fishtank is setup in the living room.Will this cause some resistance to build up in the regulator or solenoid and somehow damage it.

get co2 tubing. bioplast and Nature have it.

I got mine from nature. 10 metres.!

Hi,
what the advantage of using co2 tubing,and how much does it cost per metre?

**budak** · 29th Dec 2002, 10:33

what i hear is that CO2, being mildly acidic, will cause some corrosion and eventual leakage on normal tubing.

co2 is a neutral gas
h2co3 is an medium strength acid
the reason why people think carbonic acid is a weak acid is because co2 resists the transition into h2co3
anyway, co2 doesn't corrode the tubing directly

Hi,
Can I know how much does a metre of co2 tubing cost?
How long can the normal air tube last?

**DEA** · 29th Dec 2002, 21:12

normal airline tubing and co2 'proof' airline tubing will last about the same time
i don't anticipate them failing in the forseeable future

co2 proof tubing (the branded stuff) is over 20 bucks for 5m
you can go to kelantan lane and look for teck soon huat
they sell pneumatic airline tubing (bring aquarium airline tubing for them to check the internal diameter)
about 1 dollar per meter

Hi DEA,

Do you think you can kindly tell me teck soon huat's shop unit number or by any chances you have his shop tel number.

Thanks.

anyone can confirm these figures? think read somewhere but couldn't find the article.
pvc tubing -&gt; 40% loss
silicon tubing -&gt; 10% loss
co2 proof tubing -&gt; 5% loss

neither of the above, i'm afraid
you noe the pasar malam there?
if you're looking at sim lim towers, it's in the blocks behind there, ground floor

they sell pneumatic tubing

Hi,
Down there got many shop houses but which one is correct?

Is pneumatic tubing co2 proof?

Thanks.

**DEA** · 31st Dec 2002, 18:51

if i could tell you which one it was, i'd likely have the exact unit number, yeah?
the name is on the front of the shoo
iirc it's in one of the two blocks facing each other

pneumatic tubing should be quite resistant to gas leaking, considering they're used for high pressure applications
