Diffuser Stone, Ceramic: 9 inch long (23 cm) x 1-1/2" width, with 1/2" NPT CPVC fitting.

Our ceramic fine-pore diffusers have a smaller pore size than many diffusers, which produces finer bubbles.  The bubble uniformity is excellent and can be cleaned many times in muriatic or citric acid for years of use.

Dimensions:

• Legth: 9"
