Water changes and dosing fix problems after the fact, but pH and ORP swings are often the earliest sign something in the tank needs attention. The HYDROS Control X3 by CoralVue adds pH and ORP monitoring on top of standard equipment automation, catching those swings while there's still time to act.
Why pH and ORP Monitoring Matters
pH drift and ORP (oxidation-reduction potential) changes often show up before other, more obvious problems become visible — a slowly falling pH from a fading kalkwasser reactor, or an ORP crash signaling a decaying detritus pocket, can both be caught by continuous monitoring long before livestock show visible stress.
What the Control X3 Offers
- Built-in pH/ORP monitoring alongside the equipment scheduling and automation every HYDROS controller provides.
- Real-time alerts through the HYDROS app if readings move outside your set range.
- A middle-tier option between the entry-level X2 and the flagship X4, for keepers who specifically want water chemistry monitoring without paying for the X4's full feature set.
Choosing a Package
- Control X3 — standalone unit for keepers with existing compatible equipment.
- X3 Starter Pack — a complete, ready-to-run kit built around the X3.
- X3 Monitor Pack — a monitoring-focused kit that also watches temperature and leaks out of the box.
- X3 Pro Pack — pairs the X3 with the eight-outlet Control XP8 for a complete hardwired monitor-and-control system.
