BiOrb Replacement Airstone Having healthy fish requires proper distribution of oxygen throughout your aquarium. The biOrb Air Stone is located at the base of the aquarium and breaks up the flow of air into the aquarium into a large, beautiful mass of healthy bubbles. Not only are the air bubbles attractive and fun to watch, they add necessary oxygen flow to the aquarium for the benefit of your fish.
After time, the biOrb air stone may become clogged due to regular impurities that develop in the aquarium and calcification, especially in areas with hard water. When the air stone gets clogged, it reduces the required flow of air and oxygen into the aquarium. If oxygen levels in the tank get low enough, your fish can experience stress. To avoid stress, replace your air stone every few months. A clean air stone will bubble away quite nicely to distribute plenty of oxygen through the biOrb for the benefit of your fish.
