Fluval Plant and Shrimp Stratum – 8.8 lbs (Aquarium Substrate for Freshwater Tanks)

The Fluval Plant and Shrimp Stratum is more than just decoration—it’s a functional substrate designed to support the growth of live plants and the health of freshwater aquariums. Unlike plain gravel or colored sand, Stratum provides essential benefits that make it the foundation of a thriving planted tank.

Made from mineral-rich volcanic soil, its porous structure allows plant roots to spread easily and absorb vital nutrients, promoting strong, vigorous growth. It also encourages the rapid colonization of beneficial bacteria, helping to maintain stable water conditions.

Stratum naturally maintains a neutral to slightly acidic pH (6.5–7.0), creating the ideal environment for tropical fish, aquatic plants, and freshwater shrimp. The small granules even provide hiding spots for baby shrimp, offering extra protection in community tanks.

By combining nutrition, biological stability, and pH balance, Fluval Stratum transforms your substrate from simple decoration into a critical part of your aquarium’s ecosystem.

👉 In short: a nutrient-rich substrate that makes live plant growth possible, stabilizes water chemistry, and supports fish and shrimp health—something gravel or sand alone cannot do.
