The EasyPro Alumina Air Stone Diffuser has a high density body, which makes it self-weighted. Also, creates finer bubbles for better aeration efficiency with no increase in pressure. Because it's inlet fittings are set into its body, this diffuser is much less likely than other types of diffusers to break or twist loose.

It is also more resistant to ozone.

This diffuser can be cleaned with muriatic acid or chlorine, and it is made in the USA.

    Got these to try in a ozone injected prefilter tank. Had to work at getting my fittings to work on the 3/8 bib, but it's blowing a good amount of bubbles.
