The KNOP Calcium Reactor, also known as "The Original One", is a well established product and is the number one selling calcium reactor in Germany for 4 years. Its unique design requires minimal injection of CO2 without the concerns of low aquarium pH. As with all calcium reactors, it provides the stability of calcium, KH as well as strontium for maximum growth of all corals. It is especially useful for stony corals and clams since it is able to maintain your calcium levels in excess of 450 ppm.
The KNOP Calcium Reactor was developed and patented by marine scientist Daniel Knop. He is recognized by many hobbyists as an expert on giant clams as seen in his literature and books. His research resulted in the finest calcium reactor available today. His unique design allows for minimal injection of CO2 for dissolving the aragonite/calcium carbonate.

| KNOP Calcium Reactor C & HD |
 |
The KNOP calcium reactor model C has been released to the market in 1994 as the first professional and commercially available calcium reactor worldwide. Since that time it has been improved constantly, and meanwhile many thousand devices are operating on all five continents. Because of its reliability, the stable construction, the easy operation and the affordable price it has become one of the most frequently sold calcium reactors worldwide, market leader in the USA and Japan. Optionally it can be equipped with a CO2 filter minimizing a CO2 carry-over.
