biOrb Air Stone – Aquarium Aeration (3.5 x 1 cm) – Uniform Bubbles, Replaceable, Fresh/Saltwater

Essential Aeration Component for biOrb Tanks: The biOrb Air Stone sits beneath the filter cartridge at the base of your aquarium, producing a fine, steady stream of air bubbles for consistent oxygen circulation and a healthier aquatic environment. Supports Efficient Oxygen Exchange: By regulating the airflow from your aquarium pump, this aeration stone ensures optimal surface movement - helping oxygenate the water and improve conditions for fish, plants and beneficial bacteria. Compact, Safe & Non-Toxic Design: Measuring 3.5 x 1 cm, this solid mineral stone is completely inert - it won’t affect pH or water quality. It’s safe for all fish and ideal for both freshwater and saltwater biOrb setups. Easy To Install & Replace: No tools required - simply remove your biOrb filter cartridge, swap out the air stone, and reattach. We recommend replacing every 3 months to maintain consistent airflow and system efficiency. Creates Calming Bubble Display: As well as supporting aquarium health, the air stone’s gentle bubble effect enhances your tank’s look and feel - ideal for biOrb owners who value visual tranquillity and fish-friendly design.
