4-in-1 device that integrates the functions of a protein skimmer, air filter, CO₂ filter, and biological filter New level of filtration All-in Skim – the first filtration system on the market that combines a high-performance protein skimmer with built-in CO₂ filtration. Ideal for marine aquariums, it simplifies equipment setup, saves space, and solves multiple problems in one smart, compact device. All-in Skim is an innovative 4-in-1 device that integrates the functions of a protein skimmer, air filter, CO₂ filter, and biological filter into a single compact design. pH Stabilization and Enhanced Living Conditions for Marine Life Thanks to its built-in air and CO₂ filters, the device actively stabilizes pH levels by reducing the amount of harmful carbon dioxide, thereby improving the living conditions for marine organisms. The ability to operate in semi-open or closed mode further increases filtration efficiency and extends the life of the filtration media. Enhanced Air Purification Efficiency The use of a Venturi connector with multiple inlets allows for the parallel connection of several CO₂ filters, increasing the effectiveness of air purification. This means better-filtered air is supplied to the aquarium, improving ecosystem stability and reducing animal stress. Advanced Biological Filtration The device also includes a biological chamber that supports the growth of nitrifying bacteria responsible for breaking down harmful nitrogen and phosphorus compounds. The extended contact time between water and the biological media improves the effectiveness of biological filtration and water quality. Reduction of Unpleasant Odors An additional air filter with activated carbon, located above the skimmer cup, helps reduce the emission of unpleasant odors, greatly improving the comfort of aquarium use in a home environment. Flexible and Efficient Pump Design The energy-efficient pump offers high performance, precise control, and the ability to connect to an external controller and float sensors, simplifying operation and automation. Additionally, the pump runs extremely quietly, preserving the peace of the room where the aquarium is located. Comprehensive Support for Stable Aquarium Conditions By combining the functions of a skimmer, mechanical, chemical, and biological filtration, along with CO₂ and odor control, the device provides a comprehensive tool for maintaining stable conditions in a marine aquarium. Pump & Controller Precise flow control – power adjustable with 1% accuracy; ensures stable biological conditions and healthier aquarium life. Automation & safety – compatible with external controllers and float valves; built-in sensors protect against dry run, overheating, and malfunctions, with error codes for quick diagnosis and worry-free operation.. Silent & energy-efficient – low power consumption and quiet operation; comfort for both aquarists and aquarium inhabitants. Feeding mode – programmable up to 3 feeding intervals; temporarily reduces skimmer output to preserve nutrients and prevent overflow. Easy maintenance – simplified cleaning and servicing; more time to enjoy the aquarium instead of technical upkeep. What comes in the set?
