The HYDROS Control Sole by CoralVue is a hybrid aquarium controller with a built-in continuous-duty dosing pump. Unlike standard dosers meant for short bursts, the Sole's stepper-driven pump is engineered to run non-stop — managing calcium reactor effluent, adding kalkwasser, dosing liquid foods, feeding sulfur reactors, and automating water changes. It works on saltwater and freshwater systems, runs standalone or as part of a HYDROS network, and sends alerts and notifications like any HYDROS device.

Frequently asked questions
What can the HYDROS Sole dose? Calcium reactor effluent, kalkwasser, liquid foods, sulfur reactor feeds, and automated water changes — at anywhere from 0.1 to 300 mL/min.
How is it different from a regular dosing pump? Its pump is rated for true continuous-duty operation, so it can run constantly (like handling reactor effluent) rather than only in short scheduled doses.
Do I need another controller to switch outlets? To control power devices, pair the Sole with a HYDROS WiFi Power Strip, Control XP8, or Smart Plug.
Building out dosing? Compare the standalone HYDROS Dosing Pump for scheduled additive dosing.
