When bubbles are small enough; the force of their buoyancy becomes close enough to the force of adhesion with solid objects. This results in the phenomenon of tiny bubbles adhering to solid surfaces. Whatever was the content of the original bubble; with time all these bubbles will have the same composition of atmospheric air if the water body is contact with air; this is the result of the process of gaseous diffusion. If you want to know what was the original composition of the gas in those bubble - it would be a guess-work and a surmise based on probability of bubble production by proximity like - CO2 diffusers, plant pearling, fish exhalation, aeration etc etc
If you have a choice, you have a problem, till you elect your choice. No choice, no problem, only consequences, learn to live with them.
