Tropical Bacto-Active 30ml – Aquarium Bacterial Supplement

Tropical Bacto-Active 30ml is a live bacterial treatment designed to establish and maintain biological balance in freshwater aquariums. It contains selected, active strains of bacteria that break down organic waste in the substrate and filter media, making it an essential tool for cycling new tanks and recovering disrupted ones.

What It Does

• Breaks down organic waste accumulated in substrate and filter media using live bacterial cultures
• Initiates and stabilises the nitrogen cycle by releasing ammonium ions that stimulate nitrifying bacteria
• Clears water cloudiness and eliminates odours caused by organic build-up
• Works synergistically with Tropical Nitri-Active to significantly reduce aquarium maturation time

When to Use It

Tropical Bacto-Active is appropriate across a wide range of situations: when setting up a new aquarium, during the active maturation period, after routine filter cleaning or substrate maintenance, following water changes, and after antibiotic or medication treatments that may have depleted bacterial flora. Regular use supports long-term biological stability.

Restoring Biological Balance

Filter cleaning, medication courses, and significant water changes can all strip beneficial bacteria from an established tank. Tropical Bacto-Active replenishes that bacterial population directly, reducing the window in which ammonia and organic compounds can accumulate to harmful levels.

Size

This listing is for the 30ml bottle. Tropical Bacto-Active is also available in 100ml and 250ml sizes for larger or multiple tank setups.

Straightforward to dose and effective across new and established aquariums alike, Tropical Bacto-Active gives keepers a reliable biological foundation — whether they're cycling a tank from scratch or recovering one after a disruption.
