Porous air stones distribute air evenly which promotes good health in fish. Air stone attaches to airline tubing and should be cleaned or changed regularly. Place in your desired position in the aquarium. Weight air stone down or cover with gravel. Adjust air flow as required with Aquatic Edge gang air valves. Clogged air stones create backpressure which shortens the life of air pumps. Test your air stone by blowing through it. Replace it if you can’t blow through it.
