The AquaFX Creep Killer is a dual electronic float switch system designed to automate your reverse osmosis water production and eliminate TDS creep. This high-low float and solenoid setup precisely controls when your RO/DI system turns on and off, ensuring that only the purest, lowest TDS water makes it into your reservoir. By preventing the initial high-TDS water from entering your storage container, it maintains water quality and significantly extends the life of your expensive RO/DI filters and membranes.

This complete kit comes equipped with everything needed for installation, though some assembly is required. The system includes a low finger float, a high finger float, a relay box, a 3/8" solenoid valve, and a 3/8" bulkhead for mounting in your reservoir. The entire unit is powered by a standard 110V plug, making it a simple and effective solution for automating your water purification process. The dual float design provides a reliable high and low water level shut-off for peace of mind.

This system is ideal for dedicated reef aquarium hobbyists who demand the highest water purity for their auto top-off (ATO) or saltwater mixing station. If you're looking to maximize the efficiency of your RO/DI unit, protect sensitive corals from TDS fluctuations, and reduce the frequency of filter changes, the AquaFX Creep Killer is a top-of-the-line solution. It provides precise, automated control for maintaining pristine water conditions essential for a thriving reef tank.
