Globally trusted for premium protein skimmers and pumps, engineered in-house for unmatched reef filtration performance.
Reef Octopus NK-200 Neck Extension
The Reef Octopus NK-200 Neck Extension is a substantial performance modification designed to increase the filtration capacity of your 200-series or 3000-series protein skimmer by adding 3 inches of neck height. This extra vertical space is vital for increasing "dwell time"—the duration air bubbles remain in contact with dissolved organics—resulting in a more stable foam head and a higher concentration of waste in the collection cup.
Crafted from premium cast acrylic, the NK-200 provides the structural integrity and clarity required for high-end reef filtration. It is particularly effective for hobbyists with heavily stocked systems who want to push their existing Regal, SRO, or XP skimmers to handle higher bioloads without purchasing a larger footprint unit. The extension is stackable, giving you the modular freedom to adjust your skimmer's performance based on your specific sump depth and nutrient export goals.
Key Features
• Substantial Height Increase: Adds 3 inches to the neck to facilitate a taller, drier foam column.
