3rd Generation Lotus Root Bacteria House for fresh water (case of 4 x 12 each)

Upgrade your biological filtration system with the Mountain Tree Lotus Root Bacteria House III, a premium ceramic bio media designed to maximize beneficial bacteria growth and deliver exceptional water quality for ponds and aquariums. Inspired by the natural porous structure of lotus root, this advanced filtration media features a unique multi-channel design that promotes superior water circulation, oxygen exchange, and biological activity throughout the filter system.

Manufactured from high-quality porous ceramic materials, Lotus Root Bacteria House III provides an enormous surface area for nitrifying bacteria to colonize and efficiently break down harmful ammonia, nitrites, and organic waste. Its open internal structure allows water to flow freely through the media while helping reduce clogging and dead spots often found in traditional filter media.

Ideal for koi ponds, bakki shower systems, sump filters, freshwater aquariums, marine aquariums, and aquascaping filtration systems, this long-lasting bio media helps stabilize water parameters and improve overall aquatic health. The durable ceramic construction maintains its integrity over time, providing reliable biological filtration even in heavily stocked systems.

Whether used in professional koi pond filtration or advanced aquarium setups, the Mountain Tree Lotus Root Bacteria House III helps create crystal-clear water and a healthier environment for fish, corals, plants, and beneficial microorganisms.
