The Red Sea Reefer Skimmer RSK-900 is a high-efficiency protein skimmer designed to seamlessly integrate into modern reef aquarium systems. Driven by a powerful PSK pump, this skimmer effectively removes dissolved organic compounds from your aquarium water, leading to improved water clarity, reduced nitrates, and a healthier environment for corals and fish. Its design focuses on delivering top-tier performance while maintaining whisper-quiet operation, making it a premium choice for dedicated aquarists.

Key features of the RSK-900 include an ergonomic diffusion chamber that evenly disperses fine bubbles without impeding water flow, ensuring maximum contact time and waste removal. The unit operates quietly thanks to vibration-absorbing components and a large air intake silencer. For user convenience, it boasts a FoamView window for easy foam height monitoring, a built-in manual neck cleaner, a precision geared valve for fine-tuning performance, and a quick-release pump holder for simple maintenance. With a compact 12.6" by 10.6" footprint and three flexible assembly options, it can be configured to fit a variety of sump layouts.

This skimmer is ideal for the serious reef hobbyist with a large or heavily stocked aquarium who demands superior filtration efficiency and user-friendly features. Its robust performance is well-suited for systems housing sensitive SPS corals or a high bioload where pristine water quality is non-negotiable. Aquarists who value quiet equipment and appreciate thoughtful design elements like the integrated neck cleaner and easy-to-adjust valve will find the RSK-900 to be an essential and reliable component of their life support system.
