Diffuser Airstone is the secret ingredient for efficient aeration! These 7" Stones are manufactured with a large base to ensure the stone is sealed to the base
correctly, forcing air out of the micro-pores in the stone. If holes are too big, you will get big bubbles. If they are too small, you don’t get adequate circulation. This stone has proved itself for more than 20 years.

This innovative aeration product has the backflow valve already built in and is easy to install. Just attach your air line to the hose barb and you’re ready to go!
