The Simplicity 320DC Protein Skimmer is a high-performance filtration device designed to maintain pristine water quality in saltwater aquariums. It utilizes a controllable DC pump and needle wheel technology to generate micro-fine bubbles, maximizing the contact time between air and water for efficient waste removal. This process effectively extracts organic compounds before they break down into harmful substances, ensuring a stable and healthy environment for marine life.
Engineered with a compact footprint and cone-shaped design, this skimmer fits easily into most sumps while delivering robust performance. Key features include an adjustable DC pump speed, a clear wedge pipe indicator for easy monitoring, and a bayonet locking collection cup for hassle-free maintenance. The assembly includes a feed button, thumbscrew adjustments for cleaning, and a collection cup drain with a cap, all supported by durable construction that ensures long-term reliability.
This unit is ideal for hobbyists managing light to heavy bioloads in tanks ranging from 160 to 320 gallons depending on stocking levels. Whether you are maintaining a medium bioload reef or a densely stocked display, the customizable settings allow you to tailor performance to your unique system requirements. Its balance of effective filtration, ease of use, and affordability makes it a top choice for saltwater enthusiasts seeking reliable protein skimming without compromising on build quality.

Had this skimmer for 5 years. No issues. Has been on a 75, 120, and currently on a 180. Once tuned runs like a charm.

Really good skimmer I would recommend. Easy to clean low power consumption. Very good experience.
