With additional accessories sold separately, it can monitor temperature, pH, ORP, and water level, and control pumps, timers, and sensors. It works well in saltwater tanks, freshwater tanks, and ponds, and it can run on its own or link into a larger HYDROS setup as your system grows.\u003c\/p\u003e\n\u003cp\u003eSetup is quick, which makes the Control X4 approachable for beginners while still offering the depth advanced hobbyists want, including two digitally isolated pH\/ORP probe ports and a 0-10V port for connecting variable-speed pumps or legacy automation gear.
