The Bubble Magus BM220-CS is a high-performance, in-sump needlewheel protein skimmer designed to efficiently remove dissolved organic compounds from your saltwater aquarium. By creating a dense cloud of fine air bubbles, it effectively strips proteins and other waste products from the water column before they can break down into harmful nitrates and phosphates. This process is crucial for maintaining pristine water quality, improving water clarity, and promoting a stable, healthy environment for corals and fish in a mature reef ecosystem.

At the core of the BM220-CS is the reliable and powerful EHEIM 1260 pump, which operates at a modest 33 watts while drawing an impressive 960 liters of air per hour. This exceptional air intake fuels the large 9-inch reaction chamber, maximizing contact time between air bubbles and water for superior waste extraction. The skimmer features a compact footprint of 9.8 by 12.2 inches and stands 22.6 inches tall, designed to operate optimally in a consistent sump water level between 9.5 and 11 inches.

This protein skimmer is an excellent choice for the dedicated aquarist managing a large, heavily stocked reef aquarium. With a robust capability for systems ranging from 315 to 450 gallons (1200L-1700L), it provides the heavy-duty filtration needed to handle significant bioloads. Its efficient performance and durable construction make it a dependable workhorse for hobbyists who prioritize nutrient export and water purity to support the health of sensitive SPS corals and other demanding marine life.
