Mountain Tree Fresh Lotus Root Bacteria House (Generation 2)
High-Performance Biological Filter Media for Freshwater Systems
15 pieces per carton | Ø 8 × 25 cm
 
The Mountain Tree Fresh Lotus Root Bacteria House is a premium biochemical filtration media designed to create the ideal environment for nitrifying bacteria.
Using a patented lotus root plus spiral structure combined with nano-pores, it delivers exceptional surface area and water retention—resulting in faster, more stable breakdown of harmful ammonia, nitrite, and nitrate.
Engineered for serious freshwater pond and koi systems where biological efficiency and fish health are critical.
 
Why This Bacteria House Performs So Well
Vast specific surface area – up to 3,380 m² per litre
Patented lotus root + spiral design – over 3× more surface area than conventional media
80% water absorption rate – maximises bacterial activity
Highly stable ceramic structure – long service life
This media is designed to outperform standard bio media in both efficiency and longevity.
 
Optimised for Beneficial Bacteria
Special lotus root channels trap water and oxygen
Nano-pores provide protected micro-habitats for nitrobacteria
Encourages dense, stable bacterial colonies
Enhances conversion of ammonia → nitrite → nitrate
The result is clearer water and reduced biological load on the system.
 
Filters & Mineralises Water Simultaneously
Unlike inert media, the Mountain Tree Bacteria House actively contributes to water quality:
Contains essential minerals including K, Mg, Fe, Zn, Na, Ca
Minerals slowly dissolve, improving water balance
Supports digestion, blood condition, bone growth, and appetite
This dual action benefits both filtration performance and fish vitality.
Far Infrared & Mineral-Enhanced Ceramic
 
Manufactured using advanced ceramic technology with:
Far-infrared super ceramics
Added gem minerals, silicon ore, germanium, and tourmaline
 
These elements:
Promote “active” water
Support fish metabolism and immune response
Encourage vigorous, healthy growth
Highly valued in koi and ornamental fish systems.
