The Dennerle Carbo START FLEX200 set is a perfect composition for a successful CO2-supply in the aquarium. The set includes a Carbo START precision pressure reducer, an adapter for reusable CO- cylinders, a special non-return valve, a hose, a long-term test to determine the CO2 content and an addition device.
So everything is included except for a CO2-bottle to start CO2-fertilisation. It is entirely up to the user to choose the CO2 cylinder, as the adapter allows the use of both reusable and disposable cylinders. The powerful Carbo START pressure reducer ensures a reliable CO2-supply. The Dennerle CO2-diffuser Ultra M with integrated bubble counter and a very fine atomisation thanks to the ceramic membrane ensures a successful addition. This diffuser can be used in aquariums with a volume of up to 200 litres. The continuous glass test can be used to constantly check the current CO2 content, for example with Aqua Rebell CO2 Check. The Flex200 Special Edition includes an additional solenoid valve for night shut-off to enable an even more precise supply of CO2.
