The Deltec 400i is a high-performance internal protein skimmer engineered in Germany for discerning reef aquarium hobbyists. Designed for superior organic waste removal, it combines exceptional efficiency and reliability in a compact footprint. Its core function is to create a dense foam that extracts dissolved organic compounds from the water column, leading to improved water clarity, reduced nutrient levels, and a healthier environment for corals and fish in saltwater systems.

This model boasts whisper-quiet operation thanks to an integrated air silencer and a highly efficient DCC 1 DC pump that consumes only 9 watts of power while drawing an impressive 300 liters of air per hour. Key innovations include a cylinder body that maximizes air-water contact time, a hollow footplate for improved water flow dynamics without increasing height, and a micro-adjuster for precise water level control. For added peace of mind, an emergency overflow system prevents the collection cup from overfilling, and the entire unit can be disassembled without tools for effortless cleaning and maintenance.

The Deltec 400i is the ideal choice for aquarists with tanks from 30 gallons (heavy bioload) to 85 gallons (light bioload) who prioritize premium build quality, silent performance, and user-friendly features. Its compact 8.25" x 5" base makes it perfect for setups with limited sump space, offering top-tier German craftsmanship and performance without compromise. This skimmer is for the reefer who wants a reliable, set-and-forget piece of equipment that consistently delivers excellent results.
