Not ignorant. That's what I did.
A 2 litter bottle in a 55 gallon is hardly going to make a dent. Two would be more efficient. Most people use a "bubble counter" (if you youtube DIY CO2
you'll see what I mean) or get high-tech with valves and such.
I'm a cheap student with minimal tech ability, so I just stuff an airstone in the end of the tubing and let the vapor pressure work it's magic. I set the airstone inside the back of my filter so the filter can disperse it (trying that this time after seeing build thread where the guy used his filter as a diffuser)
Last time I just dropped the tubing/air stone in the tank and let it go.
No sick fish, no dead plants, no fluctuating water parameters... but again, 1 bottle in a 55 gal
is hardly anything. I have easy beginner plants too (java fern, anubias, crypto) so I'm sure this is a very "bare-bones" set up that won't work for high-end planted tanks.
