TheRed Sea ReefControl grounding probe (ref. R35838) is an essential accessory to optimize the safety and electrical stability of your reef installation. Compatible with the ReefControlecosystem, it guarantees reliable soil measurement and allows advanced monitoring of your equipment.
TheRed Sea ReefControl grounding probe – P/N R35838 is designed to integrate seamlessly with the intelligent ecosystem Red Sea "ReefControl", providing advanced supervision of your aquarium setup. It allows for the efficient detection and monitoring of land potentials, ensuring equipment protection, performance stability and peace of mind for demanding aquarists.
In a high-performance reef system, **electrical safety** and **equipment stability** are as important as water chemistry. By integrating the R35838 earthing probe into your rack or tank, you benefit from an additional level of supervision: detection of earth anomalies, protection of your pumps, skimmers, lighting and automatic dosing system. This helps to extend the life of your equipment, avoid unplanned interruptions, and maintain a stable atmosphere for your corals.
The probe is directly compatible with Red Sea's ReefControl controllers (Pro or Lite) and integrates via the same management interface. During installation:

To take full advantage of this accessory, check that your electrical installation is properly grounded, and set an alert in the app ReefControl if the ground value exceeds a critical threshold. This way, you anticipate any risk of electrical attack or leakage that could affect your reef rack.
⚠️ Although designed for reef use, make sure the mounting location follows the manufacturer's instructions. If in doubt, have your installation checked by a qualified professional.
The grounding probe Red Sea ReefControl eliminates parasitic voltages in the aquarium water. It contributes to the electrical safety of your reef system and protects fish, corals and sensitive equipment.
It connects to the earthing socket of your electrical installation. If there is a current leak from a pump, heater or other device, the sensor redirects this voltage to the ground, preventing any electrification of the water.
Yes, it is part of Red Sea's ReefControl range and integrates seamlessly with the ReefControlcentral controller, allowing for smart monitoring and increased security of your connected aquarium.
Yes, the probe can work standalone as a conventional grounding device, but it offers advanced tracking and integration features when connected to the ReefControlsystem.
The probe should be placed in the technical compartment (sump) or directly in the main tank, in a well-stirred area. It is easily attached using a suction cup or a suitable holder provided by Red Sea.
A grounding prevents the build-up of electrical current in the water, which can stress or injure fish and damage equipment. It increases the overall safety of the system, especially in reef aquariums where many electrical devices are in constant operation.
