Ever use airpump to diffuse CO2 into tank?

I see people use power heads and cheap filters as diffusers. What about using an airpump?

How would using an air pump work?

I'm a little unclear too . . . are you thinking a pump in combination with a yeast+sugar reactor?

Yes, with soda bottles filled w/ CO2 receipe. I see people using diffusers out of power heads w/ the line. I figure the purpose is to disperse the co2 bubbles over the tank. Wouldn't an airpump attached to a diy diffuser disperse the bubbles? Curious.

Air pumps don't usually have an inlet connections ....

Most dont, but there are plenty that do.


Use an Aqualifter. I don't see any reason why it wouldn't work. Only issue I'd see is you wouldn't be able to see whether it was still producing by looking at the airstone/diffuser.

Wouldn't the air pump create a vacuum and suck the mixture out of the bottle and into the pump/tank?

I was thinking more along the lines of the airpump blowing air to disperse the CO2. Like taking a bottle, putting the airline in one side and the CO2 line in the other. So the diffuser would have a cap, and the air would spread the mixture of bubbles throughout the tank.

Umm, that would not be in any way helpful.
In fact, what you describe would help CO2 leave the water faster, ensuring lower CO2 levels.

I don't think it would do anything to help, and could easily lead to higher co2 loss.

Only if the vessel is sealed.

im lost in what the air pump would do period...

as pressure builds inside the soda bottle, this drives the CO2 out of bottle and into the system.

if u add air to the system... ur defeating the point in generating co2 though yeast.
And if it have it set to suck the yeast bottle, eventually you will also suck all the air inside the bottle, cause it to implode a little until you got yeast mixture messing up your pump.
