The Red Sea Reefer RSK-900 is a high-performance protein skimmer engineered to meet the demanding needs of the modern reef hobbyist. Designed for superior waste removal, its highly effective flow dynamics maintain an optimal ORP (REDOX) level over 350mv, promoting a healthier and more stable aquatic environment. This skimmer efficiently removes dissolved organic compounds from your aquarium water, resulting in enhanced water clarity and improved coral and fish health without the need for additional ozone treatment.

The RSK-900 is packed with user-friendly features for maximum efficiency and convenience. Its ergonomic diffusion chamber evenly disperses fine bubbles from the PSK pump across the skimmer cone for optimal contact time, while vibration-absorbing components and a large air intake silencer ensure quiet operation. Key features include a built-in manual neck cleaner, a Foam-View window for easy monitoring, a precision geared valve for fine-tuning performance, and a quick-release pump holder for simple maintenance. With a footprint of 11.4" x 10.6" or 12.6" x 9.4" and a height of 23 inches, its three flexible assembly options allow for versatile positioning within your sump.

This protein skimmer is ideal for the dedicated reef aquarist with a large, heavily stocked system who prioritizes performance, quiet operation, and ease of use. The combination of advanced features like the integrated neck cleaner and precision control valve, along with its flexible installation and simple maintenance, makes the Reefer RSK-900 an excellent choice for hobbyists seeking to maintain pristine water quality and achieve a thriving reef ecosystem with a reliable and thoughtfully designed piece of equipment.
