Bubble algae is a form of pest algae, which can spread rapidly in a marine aquarium. It does not cause harm to fish or corals but can become a nuisance if not kept under control.
There are three effective methods for dealing with bubble algae in the reef aquarium:

- Physical removal: Can be easily removed manually by hand or syphoned out of the tank. Avoid bursting the algae bubble as they contain spores which will spread the algae to other parts of the aquarium.
- Natural predation: Introducing a herbivorous orgasm that consumes bubble algae such as an emerald crab (Mithrax sculptus).
- Denial of resources: Including nutrient removal and blocking the algae from light to prevent photosynthesis.
These methods are described in more detail in the following articles:
