Bubbles on Plants

[Goatman]

I'm curious if it is possible to produce oxygen bubbles on my plants with my current setup. Its a 55g with 108 watts 5500K CF lighting, DIY CO2 that holds around 12-15ppm, inert gravel substrate, seachem flourish fertilizer, and a decent fish load (16 fish, all at about 1"). If not, what can I do to increase photosynthesis without changing substrata or investing in a CO2 bottle (I really don't have any interest in going that direction). Any help would be appreciated.

Depends on the plant species, what are they?

You will get some pearling. To increase photosynthesis you need to either increase light or C02, or both. How do you get an odd, (odd as in wierd) number like 108 watts?

I have 4x 27w Philips CF (incandescent replacement type) 5500K bulbs. As for plant species I have something called "green frill", bacopa monieri, anachris, wisteria, and 3 species from local waters (Upstate NY).

Every week when I prune my plants they all have bubbles (streams of them) from where I trim them.

I have over 400 watts on my 100gal tank with CO2.

What ppm of CO2 do you usually run at, and what is your dosing regimen with what kind of fertilizer? I just changed the location of the powerhead misting my CO2 and the plant growth exploded, about 3/8" on my moneywort and anachris, about 1/2" on one of the local plants (very curly stemmed with little yellow underwater flowers), and about 1.5 inches on my grass. Hopefully I'm getting closer to optimum.
