Available in two Gen 2 sizes, Mountain Tree Lotus Root Bacteria House can be used in shower filters, bakki showers, trickle towers, multibay filters, biological chambers and custom pond filtration systems. Why Use Mountain Tree Lotus Root Bacteria House in Your Pond Filter? High-quality biological filtration is essential for maintaining healthy pond water, especially in koi ponds and heavily stocked systems. Mountain Tree Lotus Root Bacteria House Gen 2 helps: Provide a large surface area for beneficial bacteria Support the breakdown of ammonia and nitrite Improve biological filtration efficiency Encourage stable pond water quality Support healthier conditions for koi and ornamental pond fish Improve water movement through filter media Work effectively in shower filters and trickle filtration systems The lotus root-style internal structure and nanoporous surface help create the right environment for bacteria to establish and perform efficiently. Mountain Tree Gen 2 Biological Pond Filter Media Mountain Tree Lotus Root Bacteria House Gen 2 is designed as a high-performance biochemical filter media for ponds. Its structure combines open internal channels with a porous surface, helping water pass through while giving beneficial bacteria space to colonise. This makes the media suitable for both oxygen-rich shower filter systems and submerged biological filter chambers, depending on the design of your pond filtration setup. The Gen 2 lotus root and spiral design provides a large surface area for bacterial growth, helping improve the biological capacity of your pond filter compared with standard filter media. Suitable Pond Filter Applications Mountain Tree Lotus Root Bacteria House Gen 2 can be used in a range of pond filtration systems, including: Koi pond shower filters Bakki showers Trickle towers Multibay pond filters Biological filter chambers Custom pond filter systems High-flow pond filtration setups Garden pond biological filters For best results, use in a well-oxygenated area of the filter where pond water can flow evenly across and through the media. Key Features of Mountain Tree Lotus Root Bacteria House Gen 2 Premium biological pond filter media Ideal for koi ponds and advanced pond filtration systems Patented lotus root and spiral structure Large surface area for beneficial bacteria colonisation Helps support ammonia and nitrite breakdown Suitable for shower filters, trickle towers and filter chambers Designed to support stable pond water quality Available in two Gen 2 sizes Suitable for koi ponds, garden ponds and custom filtration systems Mountain Tree Lotus Root Bacteria House Gen 2 Sizes and Variants Variant Piece Size Quantity Media Type Application Small Gen 2 4cm × 16.5cm 24 pieces per box Biological filter media Koi ponds, shower filters and pond filter systems Large Gen 2 8cm × 25cm 15 pieces per box Biological filter media Larger koi ponds, shower filters and high-flow filtration systems Mountain Tree Lotus Root Bacteria House Gen 2 is available in two sizes: 4cm × 16.5cm – 24 pieces per box 8cm × 25cm – 15 pieces per box Which Size Should I Choose? 4cm × 16.5cm – 24 Pieces The smaller Gen 2 size is ideal for standard koi pond filters, smaller shower filters, trickle towers, multibay filters and biological filter chambers where space is more limited. This size is a good choice for pond keepers who want flexible placement and easier distribution throughout a filter system. 8cm × 25cm – 15 Pieces The larger Gen 2 size is better suited to larger koi ponds, bigger shower filters, high-flow pond systems and filtration setups with more available space. This size is ideal where larger pieces of biological media are preferred and where strong water flow can pass evenly around and through the media. For heavily stocked koi ponds or larger filtration systems, the larger size is usually the better option where space allows. Which Pond Filter Setup Is This Media Best For? Koi Pond Shower Filters Ideal for koi pond shower filters where highly oxygenated water passes over biological media to support strong bacterial activity. Bakki Showers and Trickle Towers Well suited to bakki shower and trickle tower systems, where the open structure helps water move efficiently through the media. Biological Filter Chambers Can be used in biological sections of pond filters where stable bacterial colonisation is required. Custom Pond Filtration Systems A good option for pond keepers building or modifying bespoke filtration systems for koi ponds or large garden ponds. How to Use Mountain Tree Lotus Root Bacteria House Gen 2 Place the media in the biological section of your pond filter, shower filter or trickle tower where water can flow evenly around each piece. Avoid packing the media too tightly, as good water movement and oxygen availability are important for effective biological filtration. In shower systems, position the media so water is distributed evenly across the top layer and allowed to pass naturally through the media. Before first use, rinse the media gently with clean pond water to remove any loose dust or particles from handling and transport. How to Maintain Lotus Root Bacteria House Media Mountain Tree Lotus Root Bacteria House Gen 2 is designed to support long-term biological filtration, so it should not need frequent deep cleaning. If maintenance is required, rinse gently using pond water rather than tap water. This helps protect beneficial bacteria living on and inside the media. Avoid using harsh chemicals, detergents or high-pressure cleaning methods, as these may reduce bacterial colonies and affect filtration performance. Important Information Rinse gently before first use Do not clean with chemicals or detergents Avoid using untreated tap water for cleaning where possible Do not pack too tightly, as water flow is important Biological media may take time to mature fully Best used as part of a complete pond filtration system Performance will depend on pond size, fish stocking level, feeding rate, filter design and water flow Regular water testing is recommended for koi ponds and heavily stocked systems FAQ – Mountain Tree Lotus Root Bacteria House Gen 2 What does Mountain Tree Lotus Root Bacteria House Gen 2 do? It provides a large surface area for beneficial bacteria to colonise, helping support the biological breakdown of harmful pond waste such as ammonia and nitrite. Is this suitable for koi ponds? Yes, Mountain Tree Lotus Root Bacteria House Gen 2 is well suited to koi ponds, especially in biological filters, shower filters, trickle towers and custom filtration systems. What sizes are available? There are two Gen 2 variants available: 4cm × 16.5cm – 24 pieces per box 8cm × 25cm – 15 pieces per box Which size should I choose? Choose the 4cm × 16.5cm size for smaller or more compact filter systems. Choose the 8cm × 25cm size for larger koi ponds, larger shower filters or higher-flow filtration systems where there is more space available. Can I use this media in a bakki shower? Yes, it is suitable for bakki showers and trickle-style filtration systems where water can pass evenly over and through the media. Can it be used submerged? Yes, it can be used in submerged biological filter chambers, provided there is good water movement and oxygen availability. How long does it take for the media to mature? Biological media takes time to mature as beneficial bacteria establish. This can vary depending on pond temperature, stocking level, feeding rate and existing filter maturity. How should I clean it? Only clean when needed, and rinse gently using pond water. Avoid tap water, chemicals and pressure washing, as these may reduce beneficial bacteria.
