What Are Airstones?
Airstones also known as aquarium bubblers, are typically made out of ceramic or plastic. Airstones connect to an air pump that forces oxygen through little holes in the airstone. During this process, air bubbles circulate through the aquarium and create surface agitation. This provides more oxygen to the aquarium and creates a better environment for aquatic life. This can also make aquariums cleaner and healthier.
