About Biorb Airstone
A biOrb airstone provides oxygen to your aquarium fish via bubbles. By using a biOrb air stone, you can enhance the visual interest of your aquarium and improve the well-being of your fish. If your tank has a filter pump, a biOrb airstone can also reduce noise inside the aquarium. Conveniently available on eBay, a biOrb airstone sits at the bottom of the fish tank and automatically produces bubbles. This adds valuable oxygen to the water, which helps to prevent fish from becoming stressed. Depending on the type of fish and how many share the tank, a constant supply of oxygen may indeed be essential. An airstone is beneficial to all fish aquariums, but especially so in small tanks that do not have a filter. Although two or three tiny fish may survive adequately in a small tank without a filter pump, they will be much happier and healthier with the inclusion of a biOrb airstone.
