18 hrs ago I setup a 1.89 litter bottle with co2. The bottle is located under my tank. So it has to travel up about 4 feet. I haven't had any bubbles yet, but when I shake the bottle I get bubbles. Is this too high for bubbles to travel without going pressuzied.

Hi,
No, the 4 feet should not present a problem. I suspect
that the problem is one of leaks. Most frequently the
leak is where the tube is joined to the top of the bottle.
When I used a DIY system, I drilled a hole in the bottle
cap, and then inserted a piece of rigid tubing into the
hole. I then glued it inside and out, let it dry, and then
put a bead of silicone around it as well. Then I connected
the airline to the rigid tube and the other end to an
airstone.
I had the devils own time keeping that top from leaking
and each time I had to take the top off the bottle, it
seemed as though I would nudge the rigid tube just enough
to crack the seal.

Thanks Frank!

I don't see any visible signs of a leak. I guess if it's small and only gas escaping you might not see anything.

When I move the bottle a little I do get bubbles into the tank.

Hi
The way to find the leak is to take some liquid soap, and
mix it with water. Then pour some drops on the suspected
leak. At the location it "blows bubbles" you have found
your leak. This soapy water will also pin point air leaks
in bicycle tires, and golf cart tires and automobile tires.

If not a leak, it could be your mixture. It sounds like
it is mostly alcohol or not the correct ingredients.
Check some of the other threads on DIY CO2 generation and
then try replacing your "soup." Another possibility could
be that it is too cold. It's my understanding that cooler
temperatures retard the reaction.
