Introducing HYDROS
Aquarium Automation for Everyone

  • Every HYDROSdevice is a smart device
  • HYDROS is built to withstand saltwater
  • HYDROS is fault-tolerant to keep your aquarium safe
  • HYDROS is an automation platform you can grow with
  • HYDROS accurately monitors the health of your aquarium
  • HYDROS is versatile and expandable without extra modules
  • HYDROS is self-monitoring so you’ll always know your system status

Every HYDROS Device is a Smart Device
HYDROS is different from other aquarium automation systems. Rather than having a central brain, the HYDROS platform is distributed across devices?—each capable of being used on its own or together with other HYDROS products as part of a larger system. This means every HYDROS device is a smart device with its own CPU and scheduling capabilities.

All HYDROS Smart Devices Include:

  • HYDROSCloud, a powerful mobile app to monitor and control HYDROS devices from anywhere in the world.
  • Local monitoring and control via Wi-Fi if a cloud-based configuration isn’t for you.
  • A fast dual-core 32-bit processor that allows control decisions to be made within each device.
  • Internal health monitoring to report voltages, currents, CPU status, and the internal temperature of each device.
  • HYDROSCommand Bus connections to transfer data and power to devices and equipment.

HYDROS Devices Available in Spring 2020

HYDROS Control 2

Hydros Control 2 Aquarium Controller

A small, general-purpose device capable of performing all the main functions for your aquarium. Monitor temperature, leaks, and flow rates. Power equipment, control outlets, and more. Perfect as a standalone controller for a saltwater aquarium or freshwater planted tank. You can also use the HYDROS Control 2 as one part of a larger system. For example, you can use it control an auto top-off or auto water change system.

HYDROS Control 4

Hydros Control 4 Aquarium Controller
A larger, more powerful device with all the capabilities of the HYDROS Control 2 plus additional ports to monitor, control, and power equipment. Track temperature, pH, ORP, water level, flow, leaks, outlets and more. Control pumps, timers, level sensors, dosers, fans, solenoids, switches, cabinet lighting, and whatever else you dream up. Great as a standalone controller for a saltwater fish-only or reef aquarium or as part of a larger HYDROS system for a complex reef setup.

HYDROS Wave Engine

Hydros Wave EngineAllows pumps from different brands to work together using a single integrated flow management system. Connect DC pumps to the WaveEngine and get rid of individual controllers and power bricks for a safer, simpler, and clutter-free solution. The HYDROSWaveEngine can also supply power to other HYDROS devices through the HYDROS Command Bus.

HYDROS WiFi Power Outlets

Hydros Power 4 WiFi Power Strip

The HYDROS Power 4 WiFi Power Strip and WiFi Smart Plug are smart power outlets designed to work with the CoralVue HYDROS platform. The Power 4 has 4 x 120V AC outlets and 4 x USB ports that are WiFi controllable using the free HYDROS app for Android and iOS/Apple mobile devices. The key difference between the HYDROS Smart Plug and the HYDROS Power 4 Power Strip other than the number of controllable outlets is that the Smart Plug can measure the current and wattage of the device it is powering and alert you if it moves out of tolerance.

HYDROS is Fault Tolerant to Keep Your Aquarium Safe
HYDROS devices can be configured to be fault-tolerant. Fault tolerance enables HYDROS devices to continue operating properly in the event of the failure of (or one or more faults within) some of its components.

Critical portions of the HYDROS system can be duplicated to ensure that, in the event of a probe or sensor failure, an alternative probe or sensor is available to automatically replace it.
Configuring a system to be Fault-Tolerant adds cost and complexity, but it can also be the factor that saves thousands of dollars of delicate corals in the event of a failure. HYDROS devices can also be connected to a battery backup and will run in a low current mode while under battery operation.

HYDROS is an Automation Platform You Can Grow With
A HYDROS aquarium automation system consists of as many or as few devices as you need. From a single HYDROS Control 2 to a massive system with multiple HYDROS Control 4 units, WaveEngines, and future HYDROS products.

There is no HYDROS “Lite.” You don’t have to start with a “Junior” version only to replace it later when your needs grow. With HYDROS, you can add a piece at a time according to your needs and budget today. You don’t have to invest in a “full version” with functionality you won’t use now because you’re scared you might want it in the future.

HYDROS does not assume you have one aquarium, either. You can use HYDROS to develop a distributed system to manage multiple aquariums. Suppose you have a reverse osmosis filter and some barrels in your garage. Add a HYDROS Control 2 to manage and report water levels for you!

HYDROS Accurately Monitors the Health of Your Aquarium
All the input/output (I/O) ports on HYDROS smart devices are designed to the highest standards for industrial-grade use. The pH and ORP Probe ports are the most accurate and noise immune in the aquarium industry. You can read more about these amazing inputs in the versatility section that follows.

All analog inputs use modern high-quality dedicated analog-to-digital converters. Aquarium controllers from other brands use low-quality A/D converters that are built into a microcontroller. The timing precision of all HYDROS devices is accurate to one-hundredth of a second.

HYDROS is Versatile and Expandable Without Extra Modules
Most aquarium control systems use many different types of ports to plug in the various sensors we run on our systems. For example, your aquarium controller might only allow a temperature probe to be connected to a dedicated temperature port. But if you wanted to use an optical sensor to measure water level instead of temperature, you may be required to use a different port entirely. Or worse, you might have to purchase an entirely new module to plug in the water level sensor.

HYDROS remedies this problem with Sense Ports which allow you to connect a variety of different types of sensors to a single port type. That way, you always have the right port available regardless of the sensor you want to connect.

HYDROS purposefully limits its I/O to a select few powerful ports:

  • Sense Ports
  • Drive Ports
  • Probe Ports
  • Power Ports (Command Bus)
  • 0-10v

Control 4 Inputs

Sense Ports
The Sense Port is an entirely new concept in aquarium parameter measurement. HYDROS devices include several Sense Ports. A Sense Port is a generic input port that can accept data from numerous different types of sensors. Sense ports currently support:

  • Temperature probes
  • Optical level sensors (single and dual)
  • Capacitive non-contact liquid level sensors
  • Rope leak detectors
  • Point leak detectors
  • Flow rate sensors
  • Magnetic switches
  • Push buttons

Drive Ports
The Drive Port provides switched 12V DC power for running small lights, motors, pumps, fans, and other accessories. The exact current being supplied by each port is continuously monitored, so if a motor or pump quits drawing current or draws too much, you will be immediately notified.

Accessories that are currently supported include:

  • Auto Top-Off (ATO) pumps
  • Cooling fans
  • Cabinet LED lights
  • Solenoids to control reverse osmosis systems

Probe Ports

One of the most remarkable ports on the HYDROS Control 4 is the Probe Port. You can connect an ORP probe or a pH probe to the Probe Port. But this is no ordinary pH input! The circuitry is based on an ultra-high-quality input chip specifically designed for these types of probes. Each pH input provides digital galvanic isolation from the rest of the system. Galvanic isolation prevents interference with other accessories connected to the system like motors and pumps. Digital galvanic isolation preserves the accuracy of the measurement by converting the signal to a digital domain before crossing the isolation threshold.

0-10V Ports

The 0-10V I/O port allows HYDROS to control and receive commands from other HYDROS devices and accessories from other brands. A legacy automation system can provide input via the 0-10V Ports. They can control variable speed pumps. They can also be used to monitor simple switch closures, like push buttons or float switches.

HYDROS is Self-Monitoring So You’ll Always Know Your System Status

Every HYDROS device monitors itself. Each device measure internal temperature, power supply voltage, current consumption, wattage consumed, and the status of the CPU and other circuitry. Every HYDROS device output measures the current flow into that output so that you will know if something has failed.
