co2, rather than fine bubbles, fine mist of water?

if you had a bottle turned up side down and held under the water and this had your tube from the co2 reactor running into it so that it was filled with pure carbon dioxide then below this you put an atomiser as used in little pond bowl decorations this would create an extremely fine fog of water in the bottle of co2 so surely the tiny water droplets would absorb a lot of co2 as they travelled around the bottle before re-condensing into the water again? yay or nay? just an idea i had because i broke the little thing that held the tube in front of my pump and i have one of these atomisers. NOW it does say not to use with animals i think but theres none in my tank yet so i just want to know if it works in theory.

Interesting idea. How do you get the CO2-rich water out of the inverted bottle? I am not familiar with the Atomizer you're talking about, maybe it will work.

Inverting a co2 bottle with out an anti siphon tube would be a disaster. You would be spitting extremely cold liquid co2 into your tubing, tank, atomizer, etc.

It would be a bad scene for sure.

Uh I think (hope) this wasn't the plan. I think he's talking about an empty bottle, inverted in the tank. Yeah.

Hahah oops, I sort of glossed over it and didn't read it fully. That's what I get for posting while eating a burrito.

That idea is similar to the Dupla reactor. Extremely efficient!

With the Dupla reactor you have a chamber filler with CO2. Like a long canister. A small stream of water comes in off of the filter and trickles down a set of small plastic steps. The water passes through the CO2, kind of like the water from your atomizer idea.

co2

just to clarify i DID mean an inverted empty bottle in the tank which would be filled with co2. i will try this out and see how it works. also i will be making the co2 using yeast rather than a pressurised canister.

It costs a little more, but I would just build a powerhead reactor. I used a Maxi-Jet 400, a python gravel vac (1 5/8" diameter cut down length to size), and a pack of Maxi-Jet prefilter sponges (comes with two) all from big al's for $20. The gravel vac fits perfectly on the output of the Maxi-Jet (you can even get a higher gph model like the 600). Put a sponge on the powerhead intake for easy cleaning, and one in the tube for co2 diffusion, and you're good to go. Pretty easy to make, no drilling or what not involved, just need to cut the tube in case it's too big.

Wouldn't you have trouble with CO2 escaping from the bottom of this bottle? Not sure if this would work or not -- I s'pose there's only one way to find out.
