Red Sea DC Skimmer Upgrade Kit is a comprehensive upgrade package designed to transform an existing Red Sea Reefer AC pump skimmer into a smart, efficient, and fully controllable DC skimmer. The kit includes a high-performance PSK-DC pump, a foam wetness sensor, a new skimmer lid to house the sensor, controller cable, universal power supply, and all necessary accessories to complete the upgrade quickly and easily. The standout feature of the DC upgrade is Red Sea's patent-pending self-levelling technology, which continuously monitors foam wetness and waste levels in real time, automatically adjusting pump intensity to prevent over-skimming and collection cup overflows while maintaining consistent water aeration. Once upgraded, the skimmer integrates seamlessly with the Red Sea ReefBeat app via the ReefRun Dual Controller, allowing hobbyists to monitor skimmer status, set custom skimming schedules, receive collection cup full alerts, and control the skimmer remotely from their smartphone. Whisper-quiet in operation and more energy efficient than standard AC pump skimmers, the Red Sea DC Skimmer Upgrade Kit is an ideal and cost-effective way to bring smart skimming technology to your existing Reefer skimmer setup.
