## Long description

Tropical Bacto Active 30 ml is a concentrated liquid bacterial preparation formulated for aquarium water treatment. The product supplies live beneficial bacteria strains that support biological filtration and accelerate the establishment of nitrifying colonies. It is intended for use in freshwater and planted aquariums to stabilise the nitrogen cycle and help reduce spikes in ammonia and nitrite following tank setup, cleaning, filter changes or medication.
Advantages
The concentrate contains active, non-pathogenic bacteria selected to enhance biological filtration and shorten the maturation period of new aquaria. Regular use after maintenance procedures helps to restore microbial balance and improves water clarity without altering water chemistry. The liquid form allows precise dosing and rapid distribution throughout the aquarium water.
Suitable for
 Freshwater aquariums
 Planted tanks

 After filter cleaning or replacement
 Following medication or water changes to reintroduce beneficial bacteria
Key specifications
 Form: concentrated liquid bacterial suspension
 Volume: 30 ml
 Intended use: biological filtration support and nitrogen cycle stabilisation
 Compatible with: freshwater and planted aquaria
 Application frequency: per manufacturer dosing recommendations for initial and maintenance use
How to use
Shake the bottle gently before use to ensure an even suspension. Dose the product directly into aquarium water according to the instructions on the container, typically added to the filter inlet or distributed along the tank edge to promote rapid dispersion. Use after initial setup, after partial water changes, following filter maintenance, or after disease treatment to restore beneficial microbial populations. Avoid overdosing; follow the indicated dosage for the aquarium volume and repeat treatments as recommended to achieve stable biological filtration.
Usage recommendations
Store in a cool, dark place and avoid exposure to direct sunlight. Do not refrigerate unless indicated on the label. When using medications that are bactericidal, wait the recommended period after treatment before adding the bacterial preparation to ensure survival and establishment of the introduced cultures.
