For koi enthusiasts and pond owners, maintaining crystal-clear, healthy water is more than a goal—it’s a necessity. Koi thrive in clean, balanced environments, and the right filtration system is the backbone of any successful koi pond. Introducing the QLOZONE YCM Series Combi Drum Filter, a fully automatic filtration solution designed to take the hassle out of pond maintenance while delivering exceptional water purification results. Whether you’re a hobbyist with a small backyard pond or a professional managing large-scale koi habitats, the YCM Series is engineered to meet your unique needs with cutting-edge technology and reliable performance.

At QLOZONE, we understand that koi care should be enjoyable, not time-consuming. That’s why the YCM Series Combi Drum Filter features a fully automatic design that eliminates manual cleaning and constant monitoring. The star of the system is its drum filter crafted from high-quality SS 316L stainless steel, boasting a 70-micron filtration capability—small enough to capture even the finest debris, from fish waste to algae spores, ensuring your pond water remains pristine and free of cloudiness. Unlike traditional filters that require frequent disassembly and cleaning, our built-in auto backwash pump is controlled by both a water level sensor and timer, automatically flushing out accumulated debris at optimal intervals. This hands-off operation saves you valuable time and ensures consistent filtration performance, day in and day out.

True water purification goes beyond mechanical filtration—and the YCM Series delivers a 360-degree solution. Inside the unit, a dedicated biofilter chamber filled with K5 type PE media creates the perfect environment for beneficial bacteria to thrive. These bacteria break down harmful ammonia and nitrites, converting them into less toxic nitrates that support a healthy pond ecosystem. Complemented by an air pump for efficient aeration, the biofiltration system maintains optimal oxygen levels, keeping your koi active and healthy. To combat algae growth and harmful microorganisms, the YCM Series is equipped with UV disinfection technology, which inhibits algal growth and sterilizes water, preventing green water and fish diseases that can compromise your pond’s health.

Durability and safety are at the core of every QLOZONE product. The YCM Series features a food-grade PP case certified by SGS, ensuring it is non-toxic, corrosion-resistant, and safe for your koi and the environment. The movable electric control cabinet adds convenience, allowing you to position the filter anywhere in your pond setup without being restricted by fixed wiring. Plus, we understand that every pond is unique—our water inlet and outlet sizes can be fully customized to match your existing plumbing, making installation seamless and hassle-free. Whether you need a compact solution for a small pond or a high-capacity system for a large commercial setup, the YCM Series has a model to fit your needs.
With seven models ranging from the compact QL-YCM-C5 to the high-performance QL-YCM-06, the YCM Series offers versatility for ponds of all sizes. The QL-YCM-C5 is ideal for small ponds up to 20m³ (5284gal), with a max flow of 5m³/h (1321gal/h) and low power consumption of 124W. For larger ponds—up to 100m³ (26418gal)—the QL-YCM-06 delivers a powerful 37m³/h (9774gal/h) max flow, supported by 625W of power and triple 60W UV lamps for enhanced disinfection. Each model is engineered to deliver consistent performance, with specifications tailored to handle specific water volumes and flow requirements, ensuring optimal filtration no matter the size of your pond.

What sets the QLOZONE YCM Series apart from the competition is our commitment to customization and quality. We offer full OEM&ODM support, allowing you to tailor the filter to your brand’s needs—from design tweaks to custom branding.
