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?

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.

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.

If they could only make something to extract the co2 from the air and pump it into you're tank.
agreed! how about start inventing that

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. :hihi:

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

But tanks are already affordable, so why move past them?
I can see the progression in the technology leading to getting the CO2 out of the air in the house and putting it in the tank. It would take away the need for for tanks and refilling them etc. If it was scaled down to the extent that it was the size of an air pump it wouldn't be as obtrusive in the home as having a 20 lb tank sitting next to you stand.

I could see a company like ADA going for something like this that would be sleek and barely noticeable.

Its human nature to look for easier ways to do things or improve the way things are done, so it makes sense.

I can safely say it will never be down to that size. Oxygen concentrator commonly come in the size of a small dorm fridge. The smaller, toaster sized portable ones are only able to produce oxygen at a 2-4 lpm rate.

CO2 concentrators are much larger, and much much less common. Expecting an affordable, small unit sometime in the next millennium is a futile effort. There just isn't any market.

None of the regulators ADA sell are made by ADA. The Little, most expensive(and better one) is made by Leland, just rebranded. There isn't much technical R&D going on at ADA. Someone else will have to spend the huge some of money on making it, and ADA might rebrand it. I don't see this happening as there isn't a separate need outside of this very small market that doesn't actually exist.

Also, Oxygen concentrators are very noisy, and I'd expect a co2 one to be as well. The constant hum of a concentrator at work makes me want to gouge my eyes out.

would all the nitrogen do anything? to fish or plants?
The nitrogen would be in the form of N2 gas, which is not bioavailable to plants--unless fixed to a bioavailable form by Bradyrhizobium bacteria in leguminous plants.

On another note, it would be cool if someone invented a little pump and reactor to extract CO2 out of atmospheric gas and inject it into the tank. That would be really simple and easy.
