Aqua One airstones are long lasting and provide excellent aeration in cold water, tropical or marine set ups. You can position them anywhere in your aquarium and even bury them in the substrate or under an ornament. A stream of fresh, silvery bubbles enhances any set up. They circulate aquarium water, generating oxygen whilst providing environmental enrichment for aquarium inhabitants.
