ProAir™ Weighted Diffuser Assembly. Available in two sizes for small and large ponds, tanks, dugouts or anywhere that aeration and mixing is required. If you are building your own DIY aeration system these diffuser assemblies are ideal. Raised off the pond bottom the diffuser tubes release micro-bubbles for aeration without stirring bottom sediments.
