The Sicce CO2 Life tank-less CO2 dosing system has been seen in Europe in the freshwater aquarium trade and we wonder if the tank-less CO2 delivery system has any future for the reef aquarium hobby as an alternative to tank and regulator setups. It appears the Sicce “patented†system uses a solid carbon block and electrolysis, the method of separating bonded elements and compounds by passing an electric current through them, to deliver CO2 into the tank directly. The electrolytic reaction breaks down the water molecules into oxygen and hydrogen with the oxygen reacting with a carbon block to create CO2. This isn’t the first tank-less carbon delivery system to hit the market with others previously retailing for nearly $200 and garnering mixed reviews from planted tank enthusiasts. The Sicce system retails starting at £64.99 ($104 USD) with refill sets costing £21.49 ($35 USD). We wonder if this technology has been tested in saltwater applications. It would be interesting to incorporate a unit like this into a calcium reactor giving you more real estate under the tank or in the fish room.
