Air Stone

• INTEGRAL PART OF biOrb AQUARIUM — The Air Stone is located at the base of the aquarium, under the filter cartridge, and generates a dense mass of air bubbles from the pump's airflow.
  
• ESTABLISHES PROPER AERATION — Uniformly regulates the flow of the air bubbles to provide adequate surface aeration.
  
• DEPENDABLE & SAFE — The Air Stone is a solid cylindrical component made of mineral material. It's 1.4 x 0.4 inches (3.5 x 1 cm) in size. The stone has no effect on the water composition, so it's safe for your fish.
  
• EASY TO REPLACE — Simply remove the biOrb's filter cartridge, remove old air stone, replace with new air stone and reattach the filter. We recommend replacing the air stone in your biOrb aquarium every 6-8 weeks for best results.
• SUITABLE FOR ALL biOrb AQUARIUMS — The Air Stone fits in all biOrb aquariums. It's suitable for freshwater or saltwater setups.
