Tom, apart from "pearling", have you compared actual plant growth in terms of inches/week?

In my non-CO2 tanks, I have been supplying AIR into the HOB filter via an air pump. The filter spits out a mist of tiny air bubble(a small percent of that is CO2, of course) in the output flow. I would see a lot of "pearling" on my plants, and I never thought it could be real pearling and assumed that those were tiny air bubbles collected under the leaves and formed bigger bubbles.
