Fluval Stratum Substrates ~ Now Available at Uncle Bill's Pet Centers!
Fluval Stratum is a natural aquasoil harvested from the mineral-rich foothills of Japan’s Mount Aso volcano. This volcanic origin gives it a unique composition packed with essential minerals that aquatic plants rely on to grow and flourish.
Unlike traditional gravel or sand, Stratum is specifically engineered for planted aquariums and shrimp tanks, making it a favorite among hobbyists who want both beauty and biological performance.
Why Fluval Stratum Stands Out~
🌱 Promotes Strong Plant Growth
Its lightweight, porous granules allow roots to easily penetrate and spread, giving plants direct access to vital nutrients.
Great for:
*Faster root development
*Stronger, more vibrant plants
*Long-term nutrient availability
💧 Improves Water Quality
Fluval Stratum isn’t just about aesthetics—it actively contributes to your tank’s health. Its porous structure provides a large surface area for beneficial nitrifying bacteria to colonize, helping maintain a stable nitrogen cycle.
The result? Cleaner, healthier water for your fish and invertebrates.
⚖️ Stabilizes Water Parameters 
Fluval Stratum naturally helps buffer water toward a neutral to slightly acidic pH, which is ideal for most tropical fish, aquatic plants, and shrimp.
It can also:
*Soften water
*Reduce carbonate hardness
*Create a more natural habitat
🦐 Perfect for Shrimp Tanks
Shrimp keepers rejoice! Stratum's structure provides tiny crevices where newborn shrimp can hide from predators, increasing survival rates in community tanks.
🎨 Natural Look Without the Mess
Despite being a soil-based substrate, Fluval Stratum is designed not to discolor your water. It even helps reduce organic discoloration from elements like driftwood, keeping your aquarium looking clean and polished.
Fluval Stratum is especially useful for:
*Aquascaping and planted tanks
*Shrimp-focused aquariums
*Soft-water fish species
*Hobbyists looking to reduce reliance on liquid fertilizers
It’s a simple upgrade that can make a noticeable difference in both the health and appearance of your tank!
