The Aquario Neo CO2 Diffuser is the standard in-tank variant from Aquario's respected Neo range, featuring the same high-density sintered ceramic disc technology found in their more expensive inline diffusers but in a conventional suction-cup mounted in-tank form factor. The ceramic disc is manufactured to a fine pore size specification that generates micro-bubbles small enough to dissolve completely in the water column before reaching the surface, maximising CO2 utilisation efficiency and minimising waste.
The acrylic body is precision-machined for a clean finish that compares favourably with glass diffusers at a lower price point, and the transparent construction allows visual confirmation that CO2 is flowing correctly. The 25mm disc diameter makes this diffuser appropriate for tanks up to 80 litres, offering a larger active surface area than the smallest 20mm disc diffusers while remaining compact enough for nano and mid-size setups.
Aquario Neo products are widely used by competition aquascapers and are distributed globally through specialist planted tank retailers. The CO2 Diffuser pairs naturally with the Aquario Neo CO2 Regulator for a complete Neo-branded CO2 system, or can be used with any third-party regulator providing 0.5–2 bar working pressure.
