4 Diffuser Manifold: 4 x 3" medium-pore airstones. Airflow 0.5 - 1.5 CFM.
These weighted diffusers lay flat upon the l bottom so disturbed sediments is minimized and airstones do not become fouled or covered in muck due to the underlay which keeps the airstones out of the sediment. All assemblies are equipped with a 3/8" barbed connector for your 3/8" weighted airline.
For larger ponds and lakes deeper than 10' use our large micro-bubble diffuser assemblies.
