    With a maximum pore size of 140 microns, these stones create an intense plume of bubbles, providing excellent aeration for your aquaponics system.

    Made of 100% glass-bonded silica, these stones can be expected to last indefinitely in a clean system with pH levels of less than 8.0.

    Dimensions – 38 mm x 38 mm x 76 mm long¬† (1.5″ x 1.5″ x 3″)
    Hose fitting – OD Poly barb, 4.76 mm diam. (3/16″)

    Each one comes with bumpers (sturdy rubber O-rings), to allow proper bubbling from all sides of the stone, and to protect both the stone and your tank liner.
