Korallin C1502 Calcium Reactor with Eheim Pump, Reactor Alone > Calcium Reactors

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
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
