How Aquaforest Bio S Works

Aquaforest Bio S creates favourable conditions for the growth of beneficial nitrifying bacteria, including Nitrospirae and Nitrobacteraceae.

These bacteria play an essential role in the aquarium nitrogen cycle:

  • Ammonia Processing – Beneficial bacteria help convert harmful ammonia into nitrite.
  • Nitrite Processing – Further bacterial activity converts nitrite into nitrate.
  • Biological Filtration – Established bacterial colonies help maintain stable aquarium water conditions.
  • Organic Waste Breakdown – Supports the decomposition of food residues and accumulated organic material.

Ideal for New & Established Aquariums

New Aquariums: Helps establish beneficial bacterial populations during the initial cycling period, supporting the development of biological filtration.

Established Aquariums: Suitable for use after water changes to support bacterial activity and help break down organic waste.

New Filter Media: Helps encourage beneficial bacterial colonisation when introducing fresh biological filtration media.

  • New Aquariums: Add 1 drop per 100 litres of aquarium water daily for the first 14 days.
  • Established Aquariums: Use after water changes according to the manufacturer's instructions.
