1" Ozone Resistant Oblong Diffuser Stone (Aqua-Series)

1" Oblong Diffuser Stone (1 piece). (Tubing is not included with this stone. Please see Aqua-8 Ozone Resistant Gray Oblong Diffuser Stone and Tubing Set or Aqua-6 Ozone Resistant Oblong Diffuser Stone and Tubing Set--2 White and 1 Gray Stone for tubing and stone sets for the Aqua-Series.) Please select either the gray stone or the white stone from the dropdown. Shipping Policy: Please see our Shipping Policy Page for details. Our Official A2Z Ozone Diffuser Stones are made from crystal quartz glass and have a coarse texture. This texture allows the ozone gas to be expelled through the stone creating fine bubbles that spread the ozone evenly throughout the water.  The difference between the white stone and the gray stone is that the bubbles will be smaller with the white stone. It is simply a matter of preference, as either stone will work for your water application. This stone is exclusively for use with the Aqua-6 and Aqua-8.  Directions: Insert tubing into ozone out port on the unit,
