Fluval Stratum Premium Planted Aquarium Substrate is a high-quality, nutrient-rich volcanic soil developed to create optimal conditions for aquatic plant growth and healthy freshwater ecosystems. Its porous structure encourages the colonization of beneficial bacteria, supporting biological filtration and improving overall water quality.
Designed with beginner aquarists in mind, Fluval Stratum does not require rinsing and is ready to use straight from the bag. The carefully processed granules maintain their shape while allowing delicate plant roots to spread easily, promoting faster establishment and long-term plant health.
One of the key advantages of Fluval Stratum is its ability to gently buffer water conditions toward a slightly acidic to neutral pH. This makes it particularly suitable for planted aquariums, shrimp tanks, and community fish species that thrive in stable, natural water parameters.
The dark, earthy color enhances the visual contrast of green plants and vibrant fish, creating a professional aquascape appearance. Whether used in a fully planted aquarium or combined with hardscape elements such as driftwood and stones, Fluval Stratum provides both functional and aesthetic benefits.
