Matala circle diffusers are made from recycled rubber with specially designed pore sizes to create fine air bubbles that release into the water. They are self-weighted so won't float and are fitted with the Matala 3 section hose joiner to connect to Matala self-weighted air hose. Using this type of diffuser and hose is a much better way of aerating a pond compared to aquarium type aerators with hose that floats around in the water and looks unsightly. The Matala diffuser and self-weighted air hose are black in color and sink to the bottom so they go unnoticed in a pond.
For use as an add on diffuser, or as replacement for MEA3000 Ez-Air Kit.
Each has a 3 size barb fitting 3/8", 1/2" & 5/8"
great air diffuser
works great. Easy step down barb connector made it easy to attach
These are much better than the balls or smaller aerator discs that they sell.
