Weighted diffuser sticks are perfect for aerating and mixing in ponds, tanks, dugouts or anywhere that a need for dependable micro-bubbles are required.

If you are building your own DIY aeration system these diffuser tubes are ideal. They come in three confirgurations: a single diffuser tube, a single diffuser tube mounted on a heavy duty poly plate or a dual diffuser stick assembly with two diffusers on a large poly plate. All diffusers are self weighting so they will sink to the bottom. The diffuser sticks on plates come equipped with a barbed line connector to accept 3/8" airline.

If you have a different size air hose you can simply get a MPT x HB poly hose insert to match your hose ddiameter. The single diffuser stick has a 3/4" MPT inlet only to allow for retro-fitting your Airmax KorAir diffuser or to build your own custom diffuser according to your hose lengths.
