Product Description

The EasyPro Alumina Air Stone Diffuser has a high density, which makes it self-weighting. Because its 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.

  1. So far so good 5 Star Review

    Posted by on Jun 4th 2019

    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.
