Air Stones

Glass bonded diffuser air stones. 3" x 1.5" x 1.5" with a standard nipple barb.

With an air resistance of less than .25 psi, these glass-bonded diffusers are compatible with economical low-pressure air pumps.

Manufacutured from the highest quality ceramic available, these air diffusers are machined from a solid block of glass-bonded silica. Because dust and dirt particles up to 30 microns in size will pass right through these diffusers, there's no need for expensive air filters.

They produce a uniform medium/fine bubble and are very resistant to clogging. And when cleaning does become necessary because of a buildup of calcium precipitate or bacteria, an acid bath restores them to like-new performance.

With their round grain pore structure, low resistance to air flow, uniform porosity and resistance to clogging, these air diffusers are clearly the best available for general aquaculture aeration.
