Reef aquarium controller
Electronic control unit that monitors and controls all the parameters of the aquarium. The brain of reef automation.
Detailed explanation
The most popular controllers are: Neptune Apex (most popular, complete ecosystem), GHL ProfiLux (German, industrial precision), Hydros (new, modular).
A typical controller manages: pH, temperature, ORP, salinity, water level probes. Controls: lights, pumps, heater, chiller, ATO, dosing pumps, ozonator.
Programming allows complex automations: if the temperature exceeds 27 degrees, turn off the lights and turn on the chiller. If the pH drops below 7.8, turn off the calcium reactor.
Push notifications on your smartphone alert you to any anomaly. The web dashboard shows historical graphs of all parameters.
The cost (500-1500 euros for the complete system) pays for itself by preventing a single disaster that could cost thousands of euros in lost corals and fish.
