Hydros Control X4/XP8 Pro Pack The Hydros Control X4/XP8 Pro Pack is a high-capability HYDROS aquarium controller package that combines the advanced Control X4 with the XP8 energy bar/controller for expanded monitoring, pH/ORP input, direct 12V accessory control, 0-10V integration, and eight individually controlled AC outlets. It is built for freshwater, saltwater, reef, and equipment-heavy systems that need more complete automation than a controller-only setup. HYDROS X4 and XP8 Pro Pack Overview The X4/XP8 Pro Pack is designed as a complete monitoring and control foundation for aquariums where life-support equipment, water-parameter monitoring, outlet control, and system alerts all need to work together. The Control X4 provides four Sense Ports, two Drive Ports, two pH/ORP Probe Ports, and 0-10V input/output capability, while the XP8 adds eight 120V AC outlets with individual power monitoring. Together, they create a robust HYDROS system for reef tanks, planted aquariums, large freshwater systems, fish-only aquariums, ponds, and sump-based installations. This pack is especially valuable when the aquarium has several critical devices that should not be managed by ordinary timers or basic power bars. Heaters, return pumps, skimmers, lights, UV sterilizers, feeders, and other equipment can be connected to the XP8, while the X4 handles sensor inputs, pH/ORP monitoring, low-voltage accessories, and 0-10V control. The included temperature sensor and pH probe with calibration solutions make it easier to start with meaningful monitoring immediately, while the Command Bus connection allows the X4 and XP8 to operate together as part of one HYDROS control system. Expanded X4/XP8 Pro Pack Features Control X4 monitoring and control core: The included Control X4 provides four Sense Ports, two pH/ORP Probe Ports, two 12V Drive Ports, 0-10V input and output capability, and two Command Bus ports. This gives the package a broad mix of monitoring and control options from the start. Control XP8 energy bar/controller: The included XP8 provides eight individually controlled 120V AC outlets for aquarium equipment such as heaters, lights, return pumps, skimmers, UV sterilizers, and other life-support devices. It functions as more than a simple power bar because it is also part of the HYDROS control system. Individual AC outlet monitoring: Each XP8 outlet has individual power monitoring capability, helping the system track how connected equipment is behaving. This is useful for identifying unexpected power draw, equipment failures, or devices that are not operating normally. Four Sense Ports for safety inputs: The X4 Sense Ports can support compatible HYDROS sensors such as temperature probes, optical water level sensors, leak detectors, flow sensors, magnetic switches, and push-button switches. This allows the system to monitor multiple areas of the aquarium and sump. Two pH/ORP Probe Ports: The Control X4 can monitor pH and ORP through compatible probes. This supports reef pH tracking, ORP monitoring, calcium reactor oversight, or multiple probe applications within a single controller package. Two 12V Drive Ports: The Drive Ports provide switched 12V DC power for small accessories such as ATO pumps, cooling fans, cabinet LEDs, and solenoids. Current monitoring helps alert the user if a connected accessory draws too much current or stops drawing current. 0-10V input and output capability: The X4 can send and receive 0-10V commands for compatible devices, including variable speed pumps, push buttons, float switches, and other supported control or input applications. HYDROS Collective design: The X4 and XP8 can operate together in a Collective, allowing inputs and outputs to be shared across devices. This means a sensor connected to the X4 can influence equipment connected to the XP8, and the system can be expanded with additional HYDROS devices later. Built for critical aquarium equipment: The XP8 is designed for system-critical devices and uses a built-in 60W universal voltage Meanwell power supply with a 14A maximum capacity. It is passively cooled, runs silently, and is designed to pass ETL/UL certification. App-based operation and alerts: The HYDROS app provides remote status viewing, local WiFi access, schedules, rules, modes, alerts, and manual control from a smartphone or tablet, making the system powerful without requiring code-based programming.

It is a strong option for systems using multiple heaters, return pumps, skimmers, lights, sensors, pH/ORP probes, ATO equipment, fans, solenoids, and 0-10V compatible devices. It does not include a salinity probe port, so conductivity or salinity monitoring requires a compatible HYDROS salinity-capable controller or accessory. Setting Up Your HYDROS X4/XP8 Pro Pack Download the HYDROS app, register the Control X4 and Control XP8, connect them using the included Command Bus cable and terminators, then connect the system to a 2.4GHz WiFi network. Mount both units in elevated, protected locations with proper drip loops, complete any firmware updates, then configure the temperature sensor, pH probe, AC outlets, Sense Ports, Drive Ports, 0-10V ports, alerts, schedules, and any additional HYDROS accessories needed for the aquarium.
