## Summary description

Tetra Bactozym 10 is a capsule pack containing live bacterial strains designed to activate and seed biological aquarium filters. Each capsule delivers beneficial bacteria that establish nitrifying colonies, improve water clarity and support the biological cycle after setup or maintenance. Suitable for freshwater tanks to speed up filter colonization and reduce ammonia and nitrite spikes.

## Long description

Tetra Bactozym 10 Capsules contain live bacterial strains formulated to accelerate biological filter colonization in freshwater aquariums. Each capsule introduces beneficial nitrifying bacteria that help establish a stable biological cycle after initial setup, filter installation, media changes or major water changes. Using the product supports faster conversion of ammonia and nitrite, contributing to clearer water and a healthier environment for fish and invertebrates.
Advantages
Tetra Bactozym provides a concentrated source of live beneficial bacteria in ready-to-use capsules that are easy to dose. The formulation targets nitrifying colonies to reduce ammonia and nitrite peaks and helps establish a biologically active filter more quickly than relying on natural colonization alone. Capsules are individually portioned, which simplifies treatment after filter cleaning or aquarium maintenance.
Suitable for
Freshwater aquariums during initial setup and cycling
Filters after media replacement or deep cleaning
Systems recovering from elevated ammonia or nitrite following maintenance or stocking changes
Hobbyists wanting to speed up biological colonization without introducing untreated water or substrate
When it may not be suitable
This product is designed specifically for freshwater systems and for establishing nitrifying bacteria; it is not formulated for marine or reef aquaria where different microbial communities and salinity considerations apply. It will not instantaneously remove existing toxic compounds — biological establishment takes time and should be combined with regular testing and standard water management.
Key specifications
Form: individual capsules containing live bacterial strains
Intended use: biological filter activation and seeding
Targeted action: supports nitrification (ammonia and nitrite conversion)
Suitable for: freshwater aquarium filters and systems
Packaging: multi-capsule pack designed for individual dosing
How to use
Follow label directions for dosing based on aquarium volume. Typically, add one capsule to the filter media or directly into the aquarium water where flow distributes the bacteria through the filter. Use after initial filter installation, after replacing filter media, or following large water changes and maintenance. Continue routine water testing for ammonia, nitrite and nitrate levels and repeat dosing as recommended on the product instructions to maintain a stable biological population.
What to consider before purchase
Intended aquarium type: formulated for freshwater systems only
Tank volume and dosing requirements — check recommended dose per litre or gallon
Timing: best used during or immediately after setup, media replacement or maintenance
Complementary care: regular water testing and mechanical filtration remain necessary
Usage recommendations
For effective filter establishment, add a capsule when installing or after cleaning filter media, maintain stable temperature and aeration, and monitor ammonia and nitrite levels daily until stable. Avoid overfeeding and reduce bioload during initial cycling to support bacterial colonization.
