General information about Deltec calcium reactors

The correct calcium content is a vital requirement in keeping and growing corals successfully in a marine aquarium.

Calcium reactors are a simple approach to the addition of calcium in a marine aquarium and work by adding CO2 to lower the pH of the water to a level where it will dissolve the calcium carbonate media that is in the main body of the reactor. This gives off calcium ions and carbonate ions but also releases many other elements that are bound up in the media.

The Rowalith C+ media that is manufactured for use within these reactors is mined from prehistoric coral beds and therefore contains all of the trace elements in the correct proportions that make up the coral skeleton.

When using a calcium reactor it is usual to find that the pH in your aquarium will run at a level perhaps 0.2 lower than without the reactor due to the influence of the CO2 additions. This is not a problem. Too many people get carried away with trying to achieve a pH of 8.2-8.4 which is generally only achievable long term by kalkwasser additions. Calcium reactors have a trend towards increasing dKh whereas kalkwasser additions tend to lower the dKh long term.

Fluidised Calcium Reactors

The Reactors below are now fitted with sponges top and bottom of the reaction chamber to prevent the possibility of fluidised media entering the pump. The whole lid assembly now removes via a bayonet fitting to allow easy access to the media for filling or cleaning the reactor.

New Fluidized Calcium Reactors - 4th Generation with integral CO2 bubble counter, non return valve, probe holder and non-return valve. Optional solenoid valve with 2mtrs of cable is also available
