It's when tiny oxygen bubbles form on the leaves of your plants. Looks like the plant is covered in pearls. Super satisfying to watch, especially after a water change.

Also, make sure your light is strong enough. Weak lighting won't give you pearling, no matter how good your CO2 is. I learned that the hard way with my first low-tech tank.
