Diy Co2 Canister

[Christine1014]

Hey guys, I'm REALLY hoping you can tell me what I'm doing wrong. This whole DIY Co2 canister thing seemed so simple...

I got a 2 liter bottle, and a 500 ml bottle, drilled the holes in the lids, got the tubing in, and wanted to make sure I was going to get bubbles before joining it up to my existing Nutrafin kit... I got no bubbles, but I did get water all over my counter. It was coming from the tube that goes from the smaller bottle to the tank. (or in my case, to the gang valve).

Just so I have this right... There's ONE tube that comes out of the big bottle. It goes into the lid of the small bottle, but doesn't touch the water in there. A long tube goes from the water in the small bottle, to the gang valve. Or do I have this totally wrong?

I filled the 2 liter bottle about 1/4 of the way with sugar, then added a heaping teaspoon of yeast. I filled the bottle 3/4 of the way with lukewarm water.

Pics of my attempt are attached.... you can even see the water spilling onto the counter again!

Wrong way round I am afraid.

The idea of the smaller bottle is as a bubble counter (although it seems to have been adopted as a precautionary measure against yeast mixture entering the tank) as the bubbles from the 2 Ltr enter into the water in the small bottle and then of course rise to the air and then the accumulation of air above the water leaves to your gang valve.

This way you can count the bubbles as they go from the water to the air and therefore get some indication of how many bubbles pre in you are getting.

Seeing as you are using a gang valve, I would connect the 2 ltr directly to the gangvalve with the nutrafin to the other connection and then exit the gang valve to the 'bubble counter' and onto your diffusor.

Unfortunately even though you have the in water/in air the opposite way round this will not likely be the problem of why you have a leakage of water!!

I would seal the hose to the lid so that you can be reassured that there is not a leak somewhere in the hole where the tube is going through.
