Bio Stratum Aquarium Substrate

Collected from the foothills of Mount Aso volcano, the Fluval Stratum substrates include a powerful mix of nutrients and minerals to help nurture healthy plant growth and ideal water conditions.

Fluval Bio-Stratum is infused with dormant Bioactive Beneficial Bacteria that, once in contact with water, are activated to break down waste and kick-start the nitrogen cycle. Bio-Stratum rapidly helps reduce ammonia to help stabilise water conditions in new aquariums.

Ideal for planted, aquascaped aquariums, Fluval Bio-Stratum is a porous, non-compacting, lightweight 1-3mm powder granule which allows the finest and most delicate roots to easily penetrate and spread throughout. The unique curing and heat treatment process helps extend soil life and ensures no parasites are present.

Stimulates Strong Plant Growth
Stratum substrates contain a proprietary mix of powerful nutrients, minerals and trace elements exclusively available to plants that ensures their healthy development, growth and vibrant colours. Stratum granules are non-compacting and lightweight, which allows roots to easily develop and access the nutrients locked within them.

Maintains Ideal Water Parameters for Planted Aquariums
Supporting a neutral to slightly acidic pH, Stratum substrates are ideal for live plants as well as tropical fish and shrimp commonly kept in planted aquariums. Stratum granules provide a natural way to soften water and reduce carbonate hardness (regular KH testing is recommended), all without staining or discolouring aquarium water.
