Upgrade your water filtration system with HALF OFF PONDS K1 Bio Filter Media, the trusted choice for high-performance ponds, aquariums, aquaponics, and hydroponics systems. Designed with Moving Bed Biofilm Reactor (MBBR) technology, this advanced media provides a self-cleaning environment that supports the growth of beneficial bacteria dramatically improving water clarity and reducing harmful ammonia and nitrites.
Each piece of K1 media is engineered to tumble freely in water, ensuring constant movement and maximum oxygen exposure. This creates the ideal biological environment for nitrifying bacteria, which are essential for maintaining a stable and healthy aquatic system. With a protected internal surface, bacteria are shielded from water turbulence and aggressive cleaning, allowing them to colonize safely and perform more effectively.
Available in 1, 2, or 3 cubic foot bulk packs, this bio media is compatible with most DIY and commercial pond filter systems, aquarium sumps, and aquaponic grow beds. Whether you're maintaining a koi pond, setting up a new hydroponic system, or upgrading your fish tank filtration, K1 media is an efficient, low-maintenance solution that scales with your needs.
This media is suitable for both freshwater and saltwater environments, and its durable design resists clogging, channeling, and degradation over time. It's trusted by aquarists, growers, and pond keepers who need reliable, high-capacity biological filtration without the hassle.
- Advanced Moving Bed Filtration Technology - Harness the power of K1 moving bed biofilter media, designed to outperform traditional static filters. Each piece continuously tumbles in water, exposing its large surface area to maximum oxygen and organic waste, allowing beneficial bacteria to thrive while maintaining cleaner, clearer water in your pond filter system or aquarium setup.
- 950 m²/m³ Surface Area with Protected Zones - With 950 m²/m³ of total surface area and 500 m²/m³ of protected surface area, this media offers the ideal environment for nitrifying bacteria and higher organisms. The unique internal structure keeps them safely shielded inside the media, away from harsh currents and cleaning routines perfect for koi pond filter media or bio media for aquariums.
- Self-Cleaning, Low Maintenance Design - Unlike traditional filter pads, this moving bed bio media stays in motion, scrubbing itself clean while maintaining optimal flow. It resists clogging and channeling, making it a reliable option for pond filters, aquaponic systems, and fluidized bed filtration with minimal hands-on upkeep.
