EcoPlus® Hydrovescent Air Disc® air
diffusers are great for aerating or circulating nutrients in your tanks
or reservoirs. These air diffusers incorporate suction cup feet to keep
your Hydrovescent Air Disc® secured without fear of it moving around or
flipping. The 3 air diffusers have a built-in 3/8 in 90 degree elbow
fitting that insures the air line connects freely to your fitting and
prevents the air line from kinking at the base of the fitting. Air
diffusers are great for use with EcoPlus® or Air Force Pro® Air Pumps.
Comes in three different sizes 4 in, 6 in, and 8 in.
