Product description: Aqua Medic KR Blue calcium reactor The Aqua Medic KR Blue calcium reactor features a fully closed system with an integrated circulation pump and CO2 return. It can be installed in a bypass system, independent of the water level in the tank or filter sump. The device comes loaded with 3.6 kg of hydrocarbons. Adding CO2 helps lower the pH value in the KR Blue, leading to the dissolution of hydrocarbons. Despite the low flow rate of about 0.9 - 3.8 liters per hour, large amounts of calcium and hydrocarbonate ions are pumped into the tank, greatly benefiting the tank inhabitants. The KR Blue device is equipped with an input for a pH probe (PG 13.5). Rated for tanks ranging from 245 liters to 1020 liters. Recommended accessories:

• SP 1500 dosing pump, for continuous water supply
• Solenoid valve
• pH controller
• pH probe for CO2 addition
• Hydrocarbons and dolomite to provide calcium and magnesium
