Can I just blow into my fish tank to make co2?

Question

If I put an upside down co2 "container" of some sort in my tank, can I simply blow some bubbles into the water under the container, so the container holds my co2 and it eventually disperses into the water? Is that possible? Or should I go with the yeast method of diy co2 injection?
I want to help my plants out, I don't want to poison my fish, and I don't want the pH to drop badly because I don't have much of a buffer, I don't think.
I have four small-medium sized plants and four small fish (3 glowlights, 1black neon) in my ten gallon, and my tank is pretty new. It's 10 days old, approximately, and the ammonia and nitrites are still at 0.
Is it safe and effective to just blow co2 NOT into the water, but into an upside down container that will dissolve the stuff into the water?

Thank you :)

Answer 1

It wouldn't hurt anything, but it wouldn't be particularly effective, either. Your exhaled breath contains a lot of other things besides CO2, including oxygen (which is why artificial respiration can work) and nitrogen. Those two, especially the nitrogen, make up a large portion of your exhalations, and would take up a lot of the space in your container. I'd stick with the yeast method to make a higher level of CO2; it's more dependable, as well.

Answer 2

do you know what kinds of plants you have? most common plants don't need co2 injections. in a 10 gallon i think it would be hard keeping plants that need co2. usually plants that need co2 are kind of picky and need a lot more than just co2 -- thinks like a substrate, extra light and a lot of fertilizer.

i don't know how hard it is to get co2 to stay in the water -- don't think anyone does. there are huge arguments all the way around about how to add and not add oxygen to the water. some say airstones and some say airstones don't work. some say turbulent top water. i think it would probably be best to just follow directions.

SUre you can, but the results would be so limited that you won't see a change in your plants. That is to say it will not increase the CO2 in the tank a noticeable amount. Try building a CO2 reactor and try out CO2 on your tank before you invest in a system. Here's a link to one of many reliable designs:

Answer 4

You should be changing 25% weekly .But sort your stocking out . the Tetras need to be in groups of 6 plus . The goldfish cant live in a 26 gallon tank or with the tetras Goldfish are cold water .Tetras are tropical . The molly's need to be in groups of 6 plus and are also tropical and cant live with goldfish . The blackmoors need at least 70 gallons and are cold water fish and cant be kept with tetras or molly's .

Answer 5

I dont know about that...sounds like you might introduce unwanted bacteria into your tank.

I suggest just buying a Co2 maker, they sell them at the pet store for around $20 and it's self-regulating.

Or, buy a goldfish. Nothing makes ammonia and Co2 like fish!

Answer 6

I would have to say no. I have had aquariums all my life and never had any trouble growing plants simply with lights added extra. I fear though you will have problems as the tank was to new to set up and go ahead adding fish the ammonia will spike and kill the fish

Answer 7

It all depends on how soon you want to flush the fish down your crapper. Coming up with ideas like that lead me to believe something else: if your co2 doesn't kill them, the alcohol on your breath surely will.
