Our Aqua Medic Calcium Reactor KR Blue is a hermetically closed system with an integrated circulation pump and CO2 return. It can be mounted in a bypass, independent of the water level of the aquarium or filter sump. It comes filled with 8 lbs. hydrocarbonate. The addition of CO2 lowers the pH value in the KR Blue and the hydrocarbonate dissolves. Despite the low flow rate of app. 0.25 - 1 gph, high amounts of calcium and bicarbonate ions are delivered into the aquarium, which is highly beneficial to the aquarium inhabitants. The KR Blue is supplied with a port for a pH probe (PG 13.5). Rated for 65 gallon to 270 gallon aquaria. Recommended accessories: Dosing Pump SP 1500, for constant water supply Solenoid Valve, pH Controller, and pH Probe for CO2 addition Hydrocarbonate and Dolomite for calcium and magnesium supply.
