The already best-selling Kalkreaktor (Calcium Reactor) in Germany has become even better. It completely replaces Kalkwasser, 1 or 2-part Calcium / Buffer powder & liquid dosing. The new and improved Korallin kalkreaktor allows a simple, elegant and high efficiency production of 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 Kalkreaktor setup (ie: one with CO2 System and CaCO3 media) is expensive only at the beginning. You save money in the long term because a 5-pound CO2 refill ($12) lasts you 1.5 years on our Kalkreaktor (and only ours) while a 7-kg CaCO3 media ($42 and good enough for 2 refills) lasts you up to 1 year! And no more tedious daily Calcium dosing. A pH Controller is not required for our Kalkreaktor because there is no chance for the excessive CO2 to escape into your system like ALL other brands on the market. A pH Monitor is a nice equipment to have for fast pH measuring. Though pH Test Kit and pH Pen-monitor can still be used for this purpose. The internal recirculation flow rate of the C-1502 is around 80 g/h. Since that this is a pressurized Kalkreaktor, the dissolution of the media by the carbonized water is enhanced. The effluent rate is only about 0.25 g/h at 40 drops / min. Thus explaining the efficient CO2 & media use. CO2 is being introduced into the Eheim powerhead direct - this is the most efficient Aspirating-Venturi method. Features: Top-loading & access w/ enhanced O-ring seal 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 Integrated `industrial-grade` Brass Check Valve from German Air Pressure Systems to prevent back flow of pressurized saltwater Improved engineering for stronger water circulation and suction Secure German airline tubing connectors Medical-use Miniature Quick Disconnect Couplings w/ shut-off 3 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. Water circuit interruption in case of CO2 overdose - our exclusive CO2 Safety Feature Visual excessive CO2 check w/ ventilation valve for quick release 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 - 6.25" small foot print + 15.75" total height - external or in-sump Micro-adjustable miniature ball valve to maintain a consistent effluent drip rate Slightly larger (German size) airline tubing for more consistent water flow Strainer to protect Eheim pump from loose media particles C-1502 - Rated for up to 400g. Reactor height: approx. 15.75"; Diameter: 4.5"; Ground: 6.25"; Filling amount to 3 kg. Eheim 1048 recirculation powerhead, bubble counter & brass check valve included.
C-3002 - Rated for up to 800g.
