dzega brought up an interesting idea (gas saturation). But the focus should be on O2 levels (not CO2). Pearling would be more evident when O2 gas is already saturated.
Has anything occurred to cause the O2 levels in the tank to drop? Maybe you have changed the temperature of the tank a bit? Do you try to control the O2 in any way (surface agitation changed)?

Agreed there is no big concern here (plants are growing) but this still remains an interesting mystery.
