Pond Aeration

Glass bonded diffuser air stones.  2" x 1" x 1" 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,

This high-grade silicone air tubing is ozone-resistant and ideal for a variety of applications. It features great flexibility and is easy to use.
