The HYDROS Control Minnow by CoralVue is an aquarium monitoring controller with two built-in micro-dosing pumps. Its twin independent micro-liquid dosers precisely add two-part supplements and trace elements, while four universal Sense Ports track parameters like temperature, flow, TDS, fluid level, and leaks. Use it as a standalone controller for a saltwater aquarium, freshwater tank, or pond — or fold it into a larger HYDROS system.

Frequently asked questions
What can the Minnow dose? Two separate liquids at once — ideal for two-part calcium/alkalinity and trace elements — at set speeds up to 55 mL/min.
How is the Minnow different from the Sole? The Minnow pairs two micro-dosers with four Sense Ports for supplement dosing and monitoring. The Control Sole uses a single continuous-duty pump for demanding jobs like calcium reactor effluent and kalkwasser.
Do I need another device to switch outlets? Yes — pair it with a HYDROS WiFi Power Strip, XP8, or Smart Plug.
