Would adding carbonated water have any effect on useable co2 for plants?

Yes it would, but unless you have a plant-only tank I wouldn't bother.

I once added one liter of water that I carbonated (using a Sodastream) into a 10 gallon tank with fish in it. This was a horrible idea. Essentially what I did was cause an immediate PH swing and all the fish immediately started gasping and swimming erratically. I quickly netted them all out into another tank and managed to save them all, but I would never repeat that experiment again.

Just get a pressurized (or maybe DIY) CO2 setup, unless you are only growing plants in the tank, in which case go nuts with the soda.

Lol that is exactly what I was thinking of trying...but thank you for saving me, and my fishies the trouble haha

Still I would be interested to know if anyone else has tried something similar with fish...maybe in more gradual doses, like a liter over the course of a day

So no on anyone else having experimented with carbonated water in a livestocked tank??

Also does anybody know if liquid co2 supplements like excel or api co2 booster are effective? I'm sure they help, but will they serve as a stand in to co2 hungry species when there is no pressurized co2?

They work, but are nowhere near as effective as CO2.

In addition, some plants are sensitive to glutaraldehyde.

Thanks, I'll have to do a little research and make sure all my plants are compatible.
