Air stones/CO2 stone
- Thread starter BlueBaron
- Start date
Air stones separate the oxygen into small bubbles for better aeration and maximum oxygen dispersal.
Any air stone will do the same thing for CO2 that it does for oxygen. Whatever gas passes through it will be separated into small bubbles. It isn't the stone itself that lets off the CO2 or O2. For O2, you'll need an air pump to drive oxygen through the line, through the stone, and into the tank. And for CO2, you'll need a CO2 reactor.

Air stones just pump air (or any gass you feed into the tube.
The air stone does not seperate the oxygen out of the air when it goes through, it just pumps the air straight through.
The reason it increases the oxygen content of the water isn't that the small bubbles dissolve into the water, it's that it increases the circulation of the water in the tank, so more water gets moved to the top of the tank, and the gas exchange takes place through the surface of the top of the water.
For CO2, you need _much_ smaller bubbles, so that the bubbles actually dissolve, rather than just moving the water around.
