Sweetwater diffusers are high quality ceramic type air diffusers that are machined from a solid block of glass bonded silica. With their round grain pore structure, low resistance and uniform porosity, Sweetwater diffusers are excellent for aquaculture, wastewater and lake aeration applications. Sweetwater diffusers are engineered to produce the smallest bubble possible within the constraints of a reasonable service life. In most soft water applications, you won't need to clean them for more than a year.
