Aquario Neo CO2 Diffuser S

The Aquario Neo CO2 Diffuser S is a sleek inline diffuser that mounts directly into the filter outflow line using 13/17mm hose fittings, keeping all CO2 equipment hidden outside the aquarium for a clean aquascape. A high-density ceramic disc breaks CO2 into ultra-fine micro-bubbles that dissolve rapidly into the water column, maximising carbon dioxide uptake and minimising waste. Rated for aquariums up to 60 litres, this small-format diffuser pairs perfectly with nano filters and compact planted setups. The inline design means CO2 is injected before water re-enters the tank, ensuring thorough distribution throughout the aquarium. Constructed from food-safe acrylic and a precision-sintered ceramic element, the diffuser is easy to disassemble and clean with bleach or oxalic acid.
