Mountain Tree Bacteria House – Generation 3 (Freshwater) - 12 PIECES
Ultra-High Surface Area Biological Filter Media – 6,650 m² per Piece
 
The Mountain Tree Bacteria House Generation 3 is a next-generation biological filter media engineered to maximise nitrifying bacteria colonisation while improving overall pond water vitality.
Developed from the proven Lotus Root Spiral Bacteria House II, this upgraded version introduces a new indented lotus-root core and gear-shaped spiral structure for superior biological performance.
Designed for freshwater ponds, koi systems, and advanced filtration chambers where efficiency and space utilisation matter.
 
Why Generation 3 Is a Serious Upgrade
Massive surface area – up to 6,650 m² per piece
5,292 m² per litre – exceptional bio-capacity in compact spaces
Optimised flow dynamics – protects bacteria from shear stress
High-performance ceramic media – stable, long-term biological support
This media is built for systems where water quality, fish health, and biological stability are priorities.
 
Advanced Lotus Root + Spiral Design
The Generation 3 structure combines:
Indented lotus-root 3D core – traps and retains water and microbes
Upgraded gear-shaped spiral exterior – redirects flow to reduce pressure
Gentler water movement – ideal for sustained beneficial bacteria growth
This design increases contact time, improves oxygen exchange, and creates a highly stable environment for nitrifying bacteria colonies.
 
Biological Performance Benefits
Maximises space for nitrifying and denitrifying bacteria
Improves ammonia and nitrite breakdown
Enhances biological filtration efficiency
Supports long-term system stability
Ideal for showers, moving beds (where suitable), trickle towers, and static bio chambers.
 
Water & Fish Health Advantages
Beyond filtration, Generation 3 Bacteria House media contributes to overall system vitality:
Emits far infrared rays – promotes “active” water
Supports fish immune systems and colour enhancement
Helps reduce stress and improves metabolic activity
These benefits are particularly valued in koi and ornamental fish systems.
 
Mineral-Enriched Ceramic Composition
Contains naturally occurring minerals essential to aquatic life, including:
Potassium (K)
Magnesium (Mg)
Iron (Fe)
Zinc (Zn)
Sodium (Na)
Calcium (Ca)
 
These minerals help:
Strengthen fish bone development
Improve appetite and growth rates
Support balanced blood conditions
