These ceramic air stones produce clouds of micro-fine bubbles and are the perfect air stone to maximize the oxygen level in aquarium water. Great for all freshwater and marine aquariums. Outlasts all other air stones and diffusers. Can be cleaned and reused. Assorted sizes available.

These extremely porous airstones help to distribute air evenly. They assist in maintaining even water temperature and circulation, as well as creating exciting bubble effects. Use with standard airline tubing (sold separately).

These durable Bubble Walls make it easy to create a mist of beautiful bubbles in your aquarium. They're constructed of a tough Polycyl material, which resists clogging. However, if they do become clogged, they can be easily regenerated by puncturing tiny holes with a pin or needle. Algae accumulation can be cleaned with a soft bristle brush. You can join multiple bubble walls with the attached connectors, or they can be cut with a razor blade or pair of scissors to divide or shorten.
