Calcium Reactors are an integral part of a well-stocked marine aquarium but they must be properly functioning in order to maintain the correct levels of calcium and alkalinity. In a planted freshwater aquarium CO2 is the main "fuel" for your aquarium plants. For this reason, Elos offers CO2 equipment that is both reliable and beautiful. Far to often these small items are, the "weak link" in a system because they are made with cheap plastics or modified from other industries that don't require the same durability and reliability demanded by our systems.
