The Tunze Comline DOC Skimmer 9012 DC is an advanced, compact protein skimmer designed for efficient and quiet organic waste removal in saltwater reef aquariums. Utilizing Tunze's patented Flash Skimming Principle, it actively pulls in fine particulate matter, oily films, and dissolved organic compounds from the water column, preventing their breakdown into harmful nitrates and phosphates. This unit ensures crystal-clear water and a healthy environment for your marine inhabitants, making it a cornerstone for maintaining optimal reef tank conditions.

This skimmer boasts a powerful yet energy-efficient 12V DC pump, allowing for variable speed control and precise tuning of foam height and bubble density via an included controller. It processes approximately 400 liters per hour of air with a remarkably low energy consumption of just 9 watts. Recommended for aquariums ranging from 300 to 1,000 liters (79 to 317 US gallons) depending on tank load, it features an immersion depth of 255 to 285 mm and a skimmer cup volume of 0.7 liters. Its compact dimensions (140 x 110 x 415 mm) and Silence Magnet Holder for glass up to 15 mm thickness make for flexible placement.

The Tunze Comline DOC Skimmer 9012 DC is ideal for saltwater hobbyists seeking a high-performance, adaptable, and quiet skimming solution for mid to large-sized aquariums. Its ability to adapt to varying bioloads—from heavy SPS reefs to lightly stocked setups—and its fine-tunable DC pump make it suitable for a wide range of tank sensitivities and organic loads. Enthusiasts who prioritize precise control over water quality, energy efficiency, and a compact footprint will find this skimmer an excellent choice for maintaining a thriving and pristine reef environment.
