Could someone point me out the argument where co2’s carbonic acid doesn’t really affect the actual ph that the fish/plants feel. I need to settle an argument or someone needs to set me straight lol.

Thanks in advance!

CO2 does change real pH just like any other acid. Is this what you are looking for?
