The HYDROS Rope Leak Sensor Cable is an essential accessory for any saltwater aquarium system that utilizes automated controllers to manage water levels and prevent overflow issues. This cable extends the reach of your leak sensor, allowing you to monitor areas where a standard probe might not be sufficient. It helps ensure continuous detection of potential leaks or overflows in remote corners of the aquarium setup or even outside the tank itself, providing peace of mind for aquarists who value proactive safety measures in their reef environments. The HYDROS Rope Leak Sensor Cable comes with a one-year warranty from CoralVue, Inc., guaranteeing it to be free from defects in material and workmanship under normal use.
