Matala Hakko Circle Air Diffuser, 8" Diameter OD-8

The Matala Hakko Air Hose Diffuser is an 8" diameter self-weighted diffuser that produces medium-sized bubbles. This low back-pressure diffuser gives maximum air flow from the air pump. Can be connected to 3/8" diameter weighted hose and has three sized barb options. Note: We recommend at least one diffuser for every 20 to 25 liters of air volume when used with a diaphragm pump (to prevent excessive back-pressure).
