Hi,
I'm with Roberts on the carbonated logic. CO2 not O2
On the other hand don't give them any H2O2 unless you're desperate and tryed everything to get rid of pythium/root rot. Worked once for me but nothing to do with the aeration we aim for xD. It simply killed everything living down there.
If you want to provide more oxygen just make aerated pots. There's airpots, smartpots/texpots, and normal pots with hundreds of holes with the size of a screw to provide oxygen.
