ITEM: Package includes three (3) NEW Air Stones. The pictured item is the item
you will receive.
DESCRIPTION: The air stone breaks up the flow of air into the aquarium into a
mass of bubbles. After a time the air stone can become blocked by
calcification, especially in hard water areas, reducing the flow of air into
the aquarium. Replacing the air stone every few months will keep your aquarium
bubbling away nicely. In some hard water areas it may be necessary to replace
the airstone more frequently, but once every 6 months should be sufficient for
most owners. For use with any size biOrb or biUbe aquarium. Replacing the
airstone is extremely easy. The airstone is located in the center of the
aquarium under the filter cartridge, simply remove the filter cartridge and you
will be able to locate the airstone. A replacement airstone can simply be
pushed into place.
