AquaWiz CRA – Calcium Reactor Controller
The AquaWiz CRA is designed to take your reef automation one step further by precisely controlling both CO₂ dosing and water flow within your calcium reactor. Instead of fixed bubble rates, the CRA can be programmed hour-by-hour (24h schedule) to respond to changing coral demands. When paired with the AquaWiz KH Controller, it receives real-time KH readings and automatically adjusts CO₂ input to maintain your target alkalinity. This allows KH fluctuations to be held to a narrow band (typically within ± 0.2 to 0.6 dKH in real-world setups) The system also features a non-metal valve for flow control (with periodic flushing), auto tuning of CO₂ output, and optional pH monitoring inside the reactor. Remote monitoring and control via web interface ensures you can keep an eye on the system wherever you are.
