Aqua One Grounding Probe 4m Titanium The Aqua One Grounding Probe 4m is designed to safely eliminate stray voltage and electrical current from your aquarium, helping protect both aquatic life and aquarium keepers. Electrical equipment such as heaters, pumps and lighting can release electromagnetic energy that accumulates in aquarium water. This can lead to harmful stray voltage discharges. The Aqua One Grounding Probe dissipates this excess energy and grounds any leaking current caused by damaged submersible equipment. When connected to an RCD or GFCI safety outlet, it will also trip the circuit in the event of electrical leakage, providing an extra layer of protection for you and your aquarium. The 4m cable offers generous length for convenient installation in a range of setups.
