Korallin Calcium Reactor

PLEASE NOTE: The C4002 is the US version of the SAME REACTOR, with the only difference being the inclusion of a 110V pump in the C4002 to suit the overseas voltage. The C4002 is not a newer model!

The best-selling Kalkreaktor (Calcium Reactor) in Germany has become even better. It completely replaces Kalkwasser, 1or 2-part Calcium / Buffer powder & liquid dosing. Korallin's Kalkreaktor allows a simple, elegant and high efficiency way to produce calcium hydrogen carbonate including the necessary balanced carbonic acid. Sit back and watch your aquarium's pH and dKH being kept at optimum levels. Together with our reliable CO2 System, this is the most maintenance-free Kalkreaktor setup in the world.

Ca2+ + 2HCO3 = Ca(HCO3)2 = CaCO3 + H2CO3
Calcium + Hydrogen Carbonate = Calcium Hydrogen Carbonate = Calcium Carbonate + Carbonic Acid

A pH Controller is not required for our Kalkreaktor because there is no chance for the non-dissolvable excessive CO2 to escape into your system unlike ALL other brands on the market.

Features

Top-loading & access w/ enhanced O-ring seal

Eheim 1250 Pump included in price

'Auto-fill' Integrated Bubble Counter on one water circuit (ie: water never evaporates)

Detachable Tru-Union couplings w/ O-rings for easy handling, safe shipping, upgrading and leak proof

Improved engineering for stronger water circulation and suction

Secure German airline tubing connectors

Inlet & outlet facing same direction

Special elbow for flexible airline tubing mounting

Heavy-duty Excelon construction w/ no unsightly and fragile hangover tubing

Top pump-mounting design

Self-suction water intake by the silent Eheim pump eliminates the use of a dedicated powerhead, gravity-fed or tee-off methods. It also serves for water recirculation.

Visual non-dissolvable excessive CO2 check w/ ventilation valve for quick release - you know exactly how it is functioning, no guess work or blind operating guidelines to follow

Dual effluent outlets to suit different systems

Aspirating-Venturi technology utilizes only 10 CO2 bubbles / min. and up - most efficient use of both CO2 gas and CaCO3 media

Functions immediately, no 'break-in period' required like other brands

The most compact and versatile positioning Kalkreaktor in its class - 19cm small foot print + 60cm total height - external or in-sump

Micro-adjustable miniature ball valve to maintain a consistent effluent drip rate

Strainer to protect Eheim pump from loose media particles

Optional Extra: Korallin Check Valve (not included in price)
