made this for only about 5 $ worth of materials , and the sponge can be reused !
old ug filter uptake tube with 6 rows of 6 holes each drilled in the bottom , bottom of tube siliconed to a clay pot saucer , air stone and tubing slid down uptake tube , then diffuser snaped in place . all hooked to air pump . see how it works . pardon the blue sponge .... couldn't find any open cell foam that was black or gray , so i went with car washing sponges ..... $1.45 each . was either blue or a god awful orange or green
