The HYDROS Control X10 by CoralVue is an all-in-one aquarium controller with four built-in stepper dosing pumps, combining automated dosing and full water-parameter monitoring in a single, IP65-rated unit. Built for reef, saltwater, and freshwater aquariums, it replaces a shelf full of separate components with one app-controlled device that keeps your tank stable — whether it's a nano reef on a living-room stand or a large display in a commercial lobby.
Below is a complete, plain-English look at what the Control X10 actually does, exactly what comes in the Starter Pack, and how to get the most out of it once it's installed.

What Is the HYDROS Control X10?
The HYDROS Control X10 is a smart aquarium controller that merges two of the most important pieces of tank automation — a full-featured controller and a four-head dosing pump — into a single compact device. In a typical build, a hobbyist buys a controller for monitoring and a separate doser for supplements. The X10 does both.
With one unit you can dose liquid additives, monitor temperature, and track pH or ORP. From there it expands: add accessories to measure salinity and alkalinity, detect leaks, manage water levels, and power additional HYDROS Controls as your system grows. Everything is managed through the free HYDROS app — with no programming or coding required — and the whole system runs on the HYDROS “Smart Net,” a communication web that keeps your equipment coordinated even if a single device drops offline. All HYDROS products are engineered, assembled, and supported in the USA.
What's Included in the HYDROS Control X10 Starter Pack?
The Starter Pack is built so you can get running without hunting down extra parts. Inside the box you'll find:
- HYDROS Control X10 controller
- Power supply
- pH probe
- Calibration solutions
- Temperature sensor
- Four (4) 10 ft dosing tubing lines
- Calibration beaker
This bundle covers the essentials for monitoring temperature and pH and for running all four dosing channels right out of the box.
Good to know: Salinity monitoring requires the separate HYDROS Salinity Probe Kit, and app-based alkalinity testing uses the optional HYDROS iV isolation vessel. Both are add-ons you can grow into — the Control X10 is ready for them whenever you are.

Four built-in stepper dosing pumps
Precision is the headline. Four independent stepper-motor pumps meter fluids exactly — ideal for two-part calcium and alkalinity, trace elements, automated water changes, liquid food, and more. The heads and tubing are color-coded to keep your additive lines organized, the pumps run quietly, they can reverse direction, and they're built to be easy to service.
Complete water-parameter monitoring
Temperature and pH/ORP monitoring are ready to go with the included probe and sensor. Add the Salinity Probe Kit for conductivity-based salinity readings, and use the four Sense Ports for water-level sensors, leak detection, and other inputs. Because probes are only as reliable as their signal, the X10 is engineered to keep those readings accurate and stable.
App control with zero coding
There's no programming language to learn. If you can operate a smartphone, you can run an intelligent aquarium: tap, drag, and set schedules using simple icons and menus. Schedule each device to run at a specific time, frequency, or intensity, and use real-time data to build more advanced rules whenever you're ready.
Smart Net failsafe, alerts & alarms
Every HYDROS device talks to the others to form a resilient network that keeps your tank running even if one component is removed or shuts down. The Control also monitors the exact current at each port, so if a pump stops drawing power — or a cord gets bumped loose — the HYDROS app sends an alert before a small oversight becomes an expensive one.
Reef, Saltwater, or Freshwater — Who Is the Control X10 For?
The Control X10 is versatile enough to sit at the center of almost any tank, but a few use cases stand out:
- Reef aquariums: The flagship use case. Automate two-part or balling-method dosing to hold calcium, alkalinity, and magnesium rock-steady, while monitoring salinity, pH, and temperature — the stability that keeps coral coloring up and growing.
- Saltwater fish-only (FOWLR) tanks: Consistent temperature and pH, integrated auto top-off control, and remote alerts for peace of mind.
- Freshwater and planted tanks: Automate fertilizer and trace-element dosing, monitor temperature, and schedule lights, pumps, and other equipment from one app.
- Commercial displays & service accounts: Because the X10 can be monitored remotely and scaled by linking multiple Controls, it's a strong fit for aquarium maintenance companies and commercial installations that need reliable, hands-off parameter control between service visits.
All-in-One vs. a Separate Controller and Doser
Most automated tanks are assembled from separate parts: a controller for monitoring, a stand-alone doser for supplements, and a tangle of cables tying them together. The Control X10's advantage is consolidation — one device, one app, fewer potential points of failure, and per-port current monitoring so you know instantly if something stops working.
Established ecosystems like Neptune Systems (Apex) and GHL are excellent and remain popular, so the right choice often comes down to what you already own. But if you're building a new system, or upgrading and want your controller and dosing pump handled by a single, U.S.-supported unit, the X10 is one of the cleanest all-in-one options on the market.
Getting the Most From Your Control X10
A few field-tested habits will keep your dosing accurate and your setup trouble-free:
- Label and route your lines. Use the color-coded tubing so alkalinity, calcium, and trace-element lines never get crossed.
- Use dedicated dosing reservoirs. Sealed containers reduce evaporation and keep additives organized and consistent.
- Secure your tubing. Anchor lines in the sump with a tube holder to prevent slipping and accidental overdosing.
- Only dose what you test. Start conservatively and verify parameters with a test kit daily for the first week after any schedule change.
- Calibrate on schedule. Use the included calibration solutions and beaker to keep your pH probe accurate over time.
- Grow into salinity and alkalinity. When you're ready, add the Salinity Probe Kit and HYDROS iV to unlock automated salinity readings and app-based alkalinity testing.
HYDROS Control X10 — Frequently Asked Questions
Does the HYDROS Control X10 work with freshwater and saltwater tanks?
Yes. The Control X10 works as a standalone controller for saltwater, reef, and freshwater aquariums, and it can be added to other HYDROS Controls to build a larger system.
How many dosing pumps does the Control X10 have?
It has four independent stepper-motor dosing pumps, each capable of metering a separate additive at up to 100 mL/min, with the ability to run in reverse.
Does the Starter Pack include a salinity probe?
No. The Starter Pack includes a pH probe, temperature sensor, calibration solutions, dosing tubing, and a calibration beaker. Salinity monitoring requires the separate HYDROS Salinity Probe Kit.
Can the Control X10 run automated alkalinity testing?
Yes, with the optional HYDROS iV isolation vessel. Paired with the app and a pH probe, the X10 can perform alkalinity testing using three of its dosing heads for the sample, waste, and reagent.
Do I need to know how to code to use it?
No. The HYDROS app uses simple icons, menus, and drag-to-set scheduling. There's no programming language to learn — if you can use a smartphone, you can run the X10.
Is the HYDROS Control X10 made in the USA?
Yes. All HYDROS products are engineered, assembled, and supported in the USA.
