Tropical Bacto-Active 100ml – Aquarium Bacterial Supplement

Tropical Bacto-Active 100ml is a live bacterial supplement designed to establish and maintain the biological balance in freshwater aquariums. It contains selected strains of biologically active bacteria that break down organic waste in the substrate and filter media, accelerating the nitrogen cycle and keeping water clear and stable. Suitable for new set-ups and established tanks alike.

What It Does

• Introduces live bacteria that decompose organic matter accumulating in substrate and filters
• Initiates and stabilises the nitrogen cycle by releasing ammonium ions that stimulate nitrifying bacterial growth
• Clears water cloudiness and eliminates unpleasant odours caused by organic waste build-up
• Maintains long-term biological stability with regular use

When to Use It

• When setting up a new aquarium to accelerate maturation
• During the maturation period of a cycling tank
• After water changes or periodic filter cleaning to replenish bacterial flora
• Following antibiotic treatments to restore biological balance
• In established tanks where the biological balance has been disrupted

Synergy with Nitri-Active

Used alongside Tropical Nitri-Active, Bacto-Active significantly reduces overall aquarium maturation time, allowing fish to be introduced sooner with confidence. The two products work together to cover both organic waste breakdown and nitrification, giving a more complete biological start-up.

Available Sizes

Tropical Bacto-Active is available in 30ml, 100ml, and 250ml formats. The 100ml bottle suits most mid-size set-ups and regular maintenance routines.

For any keeper who wants a clean, stable aquatic environment without relying on chemical fixes, Bacto-Active provides a biological approach grounded in how a healthy aquarium actually functions.
