This is a genuine replacement ceramic membrane for CO2 Art's IO Series diffusers — compatible with both the IO Stainless Steel Series Diffuser and the IO Acrylic Series Diffuser (Small size). It uses CO2 Art's Nano CO2 Mist Technology, breaking CO2 down into a fine stream of tiny bubbles as it passes through the membrane's porous surface for efficient dissolution into the water column.
Ceramic membranes gradually wear down with use and can become less effective at producing a fine mist over time, so keeping a spare on hand makes it quick and easy to restore your diffuser to full performance. The membrane is designed to be easily removed and reinstalled without needing to replace the whole diffuser.
Fits the Small size of the IO Stainless Steel Series and IO Acrylic Series diffusers only — check your diffuser size before ordering.
