Free CO2 and alternative energy use in the home aquarium


This might sound crazy, but I'm bored and the discussions of carbonic acid made me think, hmm what are other sources of CO2 that might obtainable...

Anyone every sit next to their tank and breath in through the nose and out through their mouth into a straw into the tank to supply plants with CO2?

How many people breathing into a tank would it take to provide enough CO2 for the plants for a day?

Other thoughts?

It would basically do nothing. 4.5% co2.

The faster you breath, the less co2 it would have... until you pass out, at which point it would stabilize for you to repeat the cycle.

so that gets to my second question, how many people would it take? say for a 10 gallon tank.

every breath would also introduce oxygen and cause huge surface agitation, thus off gassing the co2 you put in. I do not think you would see a net gain.

If they could only make something to extract the co2 from the air and pump it into you're tank.

No. It is the same as the air we breath IN.

LOL - you really must be bored if you are thinking about this.

I don't think you would see any benefits and really how realistic or feasable is it? You would need to through a "Blow Hard" party every day. It would be really funny to see - imagine all your friends standing around the tank blowing bubbles into the water with straws until everyone passes out.....too funny.

But let's be serious here it just won't work.

Well they need to scale them down and make them affordable....it would make tanks a thing of the past

I've seen a cartoon poking fun of this actually. But yeah, unless you have nothing better to do than sit by your tank all day blowing, it's not going to work. Even if you somehow do manage to do that, it probably won't work too well.

It is a funny image. It wasn't a serious thought and I knew when I was thinking it there would be no way it would be feasible. Just being curious.

This one has actually been done. You can't achieve modern standards of desired CO2 levels, but apparently it was enough to have a positive impact on the plants. I found this reference:

I seem to also remember one fellow (same one?) was filling trash bags with exhaled CO2 while doing his daily exercise, thus saving time and producing a bit more concentrated CO2.

holy cow! that's quite amazing. I wonder how the wife would feel about trash bags of air sitting next to my tanks...
