Detect two points of reference for accurate pH monitoring. Use calibration solutions that are on either spectrum of the pH you intend to monitor. For aquaponic tanks where the pH is normally 7.8-8.5, use calibration solutions 7.0 and 10.01. For aquaponic systems where the pH is normally below 7.0, use 4.01 and 7.01 calibration solutions. 4.01 pH - The lower threshold reading your pH monitor or controller will require for use with calcium reactors for saltwater aquariums, solutions below 7.00 pH, and also most aquaponic systems. 7.01 pH - Neutral pH calibration packet. This is used by almost all pH monitors and controllers for calibration. 10.01 pH - The higher threshold reading your pH monitor or controller will require for use with saltwater aquariums or solutions above 7.00 pH Calibration packets can be stored in a cool dry area for up to 1 year.

HYDROS controllers monitor temperature, pH, ORP, and water level and can control pumps, timers, level sensors, and much more. It can be used as a standalone controller or it can be added to other HYDROS Controls to build a more extensive system. Use any HYDROS device by itself or connect multiple devices as part of a larger automated system with NO single point of communication failure. Every HYDROS product is a smart device with its own CPU and scheduling capabilities.

Measure & monitor your system's Oxidation Reduction Potential value. The 10ft cable allows for long range placement in your system. Requires HYDROS app and HYDROS Control unit- NOT included.

The HYDROS Rope Leak Sensor is a flexible material that detects the presence of water anywhere along the 9ft rope. It detects water and sends a mobile alert to your app. It will also activate an alarm on the controller for immediate alerts. The rope leak sensor plugs directly into any available Sense Port on the Control XS, Control X2, Control X3, Control X4, Control X10, or any future HYDROS Control device.
