To bubble or not to bubble?

I just made the change to a planted tank about 9 months ago and everything is great (except for some BBA) ! Most planted tanks I've seen don't have a bubbler. Is there a reason for this? I would think having a bubbler would add co2. Or am I wrong? I am no chemist! lol

It will create surface agitation which will help the gas exchange? So should help bring in oxygen and c02 into the tank.
If you're adding CO2 to the tank, you're getting larger amounts of CO2 in your tank than are in the air. Bubbling will drive the excess CO2 off until there's an equilibrium. You don't want this.

If you're not adding CO2, then bubbling will keep CO2 levels in the tank relatively close to what's in the air. You want this.
Thank you so much. I really appreciate it. I do not add CO2.
i have bubblers going in my tank while co2 is on...most will say thats stupid but I got it to wear the co2 get off the algae and give my plants enough to have real great growth..every other week I have to trim up plants so I can say I have successfully done it...
