Collected from the mineral rich foothills of the famous Mont Aso Volcano in Japan and infused with beneficial nitrifying bacteria, Bio-Stratum is specifically formulated to provide immediate biological activity and maintain ideal conditions for a thriving planted aquarium. Characterized by its non-compacting 1 mm powder granules, Bio-Stratum allows plants with even the finest and most delicate roots to easily spread throughout the porous substrate while absorbing a powerful mix of nutrients, minerals and trace elements that promote explosive growth and overall health.

The nitrifying bacteria have been conditioned to enter a dormancy phase prior to packaging that allow them to survive in dry conditions. Once the substrate is added to your aquarium water, the bacteria awaken.

First, measure your tank’s length and width in cm – for example, 90 x 60 cm. Then, consider the thickness of substrate you want – for example, 8 cm. The amount of Bio-Stratum you need (in kg) is equal to length x width x thickness divided by 1000. In our example, 90 x 60 x 8 / 1000 = 43.2 kg of Bio-Stratum needed.

We recommend gently rinsing Bio-Stratum in a large colander or similar device without agitating the substrate to remove fine dust particles.

Key Features:

Promotes healthy plant development, vigorous growth and vibrant colour
Infused with dormant beneficial nitrifying bacteria that, once in contact with water, are activated to break down waste and kickstart the nitrogen cycle
Rapidly reduces ammonia levels to help stabilize water conditions in new aquariums
Lightweight 1 mm powder format granules are non-compacting and allow even the finest and most delicate roots to easily penetrate and spread throughout substrate
Porous granules promote extensive bacterial colonization and act as an additional source of biological filtration for improved water quality
Includes a powerful mix of plant-friendly nutrients, minerals and trace elements
Helps support a neutral to slightly acidic pH – ideal for live plants as well as tropical fish and shrimp commonly kept in planted aquariums
Softens water naturally, reducing carbonate hardness
Will not stain water and helps control organic discoloration
