Tropical Bacto Active 100 ml – bacterial preparation for aquarium biological filtration and water stabilization

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.
