When I started aerating my non-CO2 tanks, I was only thinking about keeping CO2 level at least at equilibrium level in water: about 2 ppm. Maybe I am getting the unexpected benefit of those tiny bubbles. By the way, don't try connecting those CO2 diffuser discs to air pumps. The higher pressure from air pump builds up and destroys the disc in a second. Wasted my $15 diffuser.

If you use pure O2 and regulator it works well
Is 0.033% going to grow plants better or is 100% going to grow plants better?
Both are gas phases.
30ppm will work mind you, and can do quite well.
But this is definitely better, which is the revelation part.
I'm talking every odd wimpy plant species you can think of.
Suddenly growing and pearling like no tomorrow with only this one change.
Aeration adds enough CO2 for marine plants BTW, I'd like to try a non CO2 aeration tank, but as Sha lu found out, the diffuser did not work well.
I'd like to get a compressed air tank instead of the pure O2 and see if this would do well for the non CO2 method..............ah that would be cool.
The key here is bubble size, it needs to be very fine.
I know folks have tried vigorously aerating and in certain part of the tank you can see good results from this, but at higher levels of finer aeration, I wonder if this could be improved.
If so, that would be a radical change, no CO2, no CO2 dosing , no CO2 fish kills and better growth than non CO2 etc.
Dissolving O2 is not the goal, getting the bubbles very small and onto the plant leaves is the goal.
