The HYDROS DC Micro Pump is a highly efficient and compact pump specifically engineered for saltwater reef aquariums. Its primary function is to serve as the core component of an auto top-off system, working in conjunction with a HYDROS Control 2 or Control 4 unit and an optical or float water level sensor. This integration allows for precise and automated replenishment of evaporated water, maintaining stable salinity and water levels in your aquarium. Despite its diminutive footprint, measuring just 1.6” L x 1.062” W x 1.45” H, this 12V brushless pump delivers impressive performance with a maximum head pressure of 8 feet and a flow rate of 74 gallons per hour. It operates with remarkable energy efficiency, drawing a maximum of 4.5W, and boasts an average life expectancy exceeding 30,000 hours. When connected to a HYDROS controller's Drive Port, the pump receives power directly, eliminating the need for additional power cords or bricks and reducing wire clutter. This pump is an ideal choice for reef aquarists who are already invested in or planning to adopt the HYDROS ecosystem for their aquarium automation. It provides a reliable and streamlined solution for maintaining consistent water parameters, especially when paired with multiple HYDROS sensors for enhanced redundancy and safety. Manufactured by AutoAqua, a trusted name in ATO technology, the HYDROS DC Micro Pump offers peace of mind and seamless integration for a sophisticated and clutter-free aquarium setup.
