The Aqua One Extendable Air Stones circulate aquarium water, generating oxygen whilst providing environmental enrichment. By breaking the surface tension of the water, oxygen may be absorbed into the water. Filtration system performance and overall water quality will be greatly improved with a greater oxygen content in the water. The extendable air stones allow you to increase the length of your airstone by joining them together. There is no limit to how many air stones can be joined together.
