Matala Hakko Base Air Diffusers are membrane air diffuser assemblies that feature heavy-duty plastic bases with soft edges. These bases are hollow so that they can be filled with s and or gravel, eliminating the need for bricks and straps to get the diffuser to sink. Two sizes of bases are offered: the small base can accommodate one or two diffusers, and the large base can accommodate two or four diffusers. Heavy-duty diffusers produce medium bubbles, reducing back-pressure on the pump All base units come with a 3/4" FPT fitting and a multi-barb adapter with a 3/8" barb, a 1/2" barb, a 5/8" barb and a 1" barb to attach to any of those hose sizes.
