Aqua one airstone - 4 inch/10cm
Oxygen plays a vast part of having a healthy and well maintained aquarium. Many fish need more oxygen than standard filtration can supply, so having an airstone and pump running in your aquarium can ensure your fish are happy and healthy as well as giving your aquarium the added feature of bubbles being released. Air stones circulate aquarium water, generating oxygen whilst providing environmental enrichment.
