My tank's too new for pearling, but I'm hoping to see it soon. Just set up a 15 gallon with Monte Carlo and CO2. How old is your setup?


Give it a few months. Pearling usually starts once the plants are fully established and the tank is balanced. Took mine about 3 months to see consistent ...

Pearling after a water change is usually a sign of good oxygenation and CO2 levels. Your Monte Carlo is likely photosynthesizing efficiently. What's your substrate? I've seen this more often with nutrient-rich substrates like ADA Amazonia.
