Matala Disc Diffusers were originally designed for the wastewater treatment industry, and thus conform to very high standards. The air pore size in the rubber membrane is designed to give a medium-sized bubble, which contributes less than 6" of water depth back-pressure. The 3/4" male thread makes it easy to attach to your feed line.


The disc is very low maintenance and in some cases NO maintenance. Simply wash the disc with clean water and bleach if it ever needs cleaning. Some of these diffusers have been in operation for over 3 years without trouble or maintenance.
