Saraja87,

For a 110 gals. tank try to set a rate of about 1 bubble per second. If things go well, no gasping fish and such then see if the plants like it. If the plants don't seem to perk up raise the bubble rate a little - about 1.5 bubbles per second (don't immediately go to 2 bps)

You will see tiny bubbles coming out of this miracle of a reactor. "Tiny" bubbles means they look more like dust and float up very slowly (cause they are too small and don't know what they are doing, you know).

It's hard to recommend a set bubble rate. If the tank handles it well - no gasping fish, plants doing well - then this is the bubble rate you should keep.

One thing to remember is to NOT let the surface of the water be without movement. The surface movement is extremely important for gas exchange. But too much movement will waste a lot of CO2.
