Take a straw and blow into your tank every few minutes.

I once actually asked this. Your added all that you breathe into the tank co2 will dissolve quickly so...I know you couldn't help yourself but it really cannot be done.

Once thought of blowing up a large balloon and pinching off the rate of it's escape into the tank, but couldn't muster up the energy needed on just one lung.

I found this poor man's technique worked great several years ago when I was experimenting with CO2 and drop checkers. That was with a pint of water. With 10 gallons the effect is harder to get. With 55 gallons of water it ceases to be a poor man's technique and becomes an attempted suicide!>

Yes but what kinda of bubbles per second can you get?
:wink2:

Already tried this years back. I'd ride my bike around the block to build up some carbon dioxide and then re-breathe my last breath into a plastic bag to give it an extra amount of CO2, then quick into the house with my head swimming from oxygen deprivation to blow that last breath into the tank bell jars.

Really dumb.

Yeast and Sugar works fine by comparison

 

[epiphysis]

Do not attempt if you are smoker like myself.

Thanks for that laugh!

Ok, well I bet we could figure that out. But the truth of the science is, that you can't 'take a breath' and then breath into the tank. You have to have a normal period of breath, and the amount of CO2 will be substantial. So not a lot of air, just a little breath.

Yea, I think I'm really waiting for the day I find that all I need to do is piss in my tank each day, and everything will grow beautifully and live well.

This only works for cycling a tank.

You could give your fish a serious case of gill cancer.

Your exhaled breath is like 100,000 ppm by volume CO2 from what I can remember. The key is to collect the CO2. Does anybody work in the CO2 scrubbing field? What about a device that collects CO2 while the lights are off and release CO2 when needed.

Brilliant! Yes, Richard Branson is/was funding a CO scrubbing contest a few years back. I don't know if a facility has been built yet, but it's a game changer if we get good at it.

I read it a while back. There's a compound that traps CO2 naturally like activated carbon. You'd move air through a matrix of the stuff. When you need CO2 released, you apply heat.

 

[Hoppy]

Lithium hydroxide is a substance that can scrub the CO2 out of air. But, I couldn't find out how you can "withdraw" the CO2 for any use, or recycle the lithium carbonate that forms when it is combined with CO2.

There was an article on BBC news website about some new baking soda (if I remember correctly) based CO2 scrubbers, this past week, you should be able to find it with a bit of searching

edit... found it

You can store CO2 in water too! Just blow again and again and again and the water becomes carbonated. This thought makes me rethink how to make a DIY yeast sugar system that can be shut off at night. See my DIY forum post to see what this generated.

Blow up a bunch of balloons?

 

[Beamer]

Can I raise the stakes on the recklessly impractical CO2 solutions?
What about the flue gasses from your gas boiler? A nice premix burner produces a steady 9.0%CO2 and lots of it, about equal to the volume of gas that being burnt and that is measured in litres per second. Now that sort of CO2 rate would grow some plant. Save the planet a bit as well.

If anybody tries it and it and it all goes boobs up, it wasn't my idea, I was never here.

You left out another gas, CO right?

Yea, you drop a dry ice "torpedo" down to a level where the pressure ensures it stays solidified.
