## Long description

Tropical Bacto Active 100 ml is a concentrated bacterial preparation for aquarium biological filtration and water stabilization. It delivers selected live nitrifying and heterotrophic bacteria to accelerate establishment of the nitrogen cycle, reduce ammonia and nitrite peaks, and support biological processes after tank setup, water changes or filter maintenance. The formula is suitable for use in freshwater and tropical aquaria where rapid re-colonization of filter media and stable water chemistry are required.
Advantages
The preparation supplies active bacteria in a compact, easy-to-dose liquid form that quickly disperses through filter media and aquarium water. It shortens the time needed for beneficial microorganisms to develop, helping to prevent toxic ammonia and nitrite spikes. The product supports clearer water and more stable biological filtration without altering water parameters such as pH when used as directed.
Suitable for
 New aquarium setup to establish biological filtration
 After large water changes to restore microbial balance
 After filter cleaning or replacement of filter media
 When stocking new fish to reduce stress from changing water chemistry
 Freshwater and tropical community aquaria requiring stable nitrogen cycling
Key specifications
 Form: concentrated liquid bacterial culture
 Volume: 100 ml
 Intended use: biological filtration support and water stabilization
 Compatibility: freshwater and tropical aquaria
 Effect: accelerates nitrification and reduces ammonia/nitrite peaks
How to use
Shake the bottle gently before use. Dose according to container instructions for the aquarium volume; add directly to the aquarium water near the filter outflow to ensure even distribution. Use the product when setting up a new aquarium, after substantial water changes, or following filter maintenance. Regular monitoring of ammonia and nitrite levels is recommended during the initial days after application to confirm biological stabilization.
Usage recommendations
For best results, maintain stable water temperature and avoid simultaneous use of antibacterial medications or strong oxidising agents that can reduce bacterial effectiveness. Reapply after major filter cleaning or when introducing a significant fish load; follow dosing guidance based on aquarium volume and observe water parameters to adapt frequency.
