What Causes Pearling in Aquarium Plants?

FAQs Jackson Bowman August 4, 2022

This usually happens because the aquarium plant releases oxygen faster than it can be dissolved in the water at that point in your aquarium. As a result, they form bubbles that resemble small shiny beads, and the process itself is called beading.

What does it mean when aquarium plants are pearling?

Pearl plants develop because your tank is unable to hold the amount of oxygen it produces. When this happens, blisters form on the leaves of your aquatic plants. You will also see bubbles rising to the surface of the water.

Should my aquarium plants be pearling?

Essentially, any plant can produce oxygen at a rate high enough to form oxygen bubbles. If you want to strive for that, by all means keep going, just know that your plants are healthy when they show good growth and beading is just a nice side effect.

Why do aquatic plants bubble?

Tiny bubbles rising from the leaves of an underwater plant are oxygen. In a process called photosynthesis, plants use light energy to create food and oxygen from carbon dioxide and water. Although plants use a small amount of this oxygen, most of it is released as waste.

Why are my aquarium plants not getting pearls?

In my experience pearl effect is at its best in strong light and high CO2 emissions (very strong even more!). With medium PAR and light CO2 I wouldn’t expect that. And yes, beading is much more pronounced on fast growing plants with lots of light.
