Fluval Bio Stratum 4kg

Crafted from 100% natural, mineral-rich volcanic soil from Mount Aso in Japan, Fluval Bio-Stratum is infused with beneficial nitrifying bacteria to provide immediate biological activity and optimal conditions for a thriving planted aquarium. Its lightweight, non-compacting 1mm granules allow even the most delicate plant roots to spread easily, absorbing a powerful mix of nutrients, minerals, and trace elements that encourage vigorous growth and vibrant colour. Bio-Stratum rapidly reduces ammonia to stabilise water in new tanks and supports a neutral to slightly acidic pH, making it ideal for live plants, tropical fish, and shrimp. This 4kg bag is perfect for smaller aquariums or as a top layer in larger tanks. All measurements are manufacturer stated.
