A ceramic plate specifically for use with the TMC AquaGro Compact Diffuser  25mm.

All diffusers need maintenance over time and plates become dirty and algae grows on them. Quite often shrimp and other algae eaters avoid the plates due to CO2 which comes out of them. This means they don't get the attention they often need.

This is the perfect replacement if your old plate becomes dirty or simply old and needs replacing. New plates offer a better diffusion of CO2 as the plate is harder and therefore bubbles are smaller.

Tip: Remember the smaller the CO2 bubble, the higher surface area. This means better CO2 absorption which in turn means less gas is required.
