Upgrade your aquarium’s filtration system with our Large Ceramic Filter Media Tube Blocks, designed for exceptional biological and mechanical filtration. Whether you’re maintaining a home aquarium or a large koi pond, these premium media tubes provide the perfect environment for beneficial bacteria to thrive — ensuring crystal-clear, healthy water.
Premium Porous Ceramic Material
Crafted from high-quality porous ore, enriched minerals, and fine volcanic ash. Each block is heat-treated at 1800°C to create a high-density, ultra-porous structure, ideal for colonization by nitrifying bacteria.
Dual Filtration Functionality
Performs both mechanical and biological filtration — efficiently trapping debris while breaking down harmful ammonia, nitrites, and nitrates through natural bacterial processes.
High Surface Area
Provides significantly more surface area than standard ceramic rings, promoting superior bacterial growth, enhanced water purification, and improved oxygen exchange.
Versatile & Cuttable
Easily trimmed to suit your filter’s design. Ideal for canister filters, sump tanks, trickle filters, bakki showers, aquaculture systems, and koi ponds.
🪨 Stable & Long-Lasting
Made with a pH-neutral, durable composition that resists breakdown. Helps stabilize water conditions and provides consistent, long-term filtration performance.
Wide Compatibility
Perfect for freshwater, saltwater, and planted aquariums, as well as any system that requires efficient biological filtration.
Improves Water Quality & Fish Health
Reduces toxins, balances water chemistry, and supports a cleaner, healthier environment — promoting stronger fish immune systems and a more vibrant aquatic ecosystem.
