Fluval Plant and Shrimp Stratum substrate 8.8 lb — porous, mineral-rich for planted aquariums

Fluval Plant and Shrimp Stratum is a lightweight, porous substrate engineered to nourish aquatic plants and shelter shrimp in freshwater planted aquariums.

Designed for hobbyists who want healthy root development and stable water conditions, this 8.8 lb bag of Fluval Stratum combines a non-compacting texture with mineral-rich granules that encourage root penetration, bacterial colonization, and a neutral-to-slightly-acidic pH ideal for many tropical plants, fish and shrimp. It’s formulated to avoid tinting water while helping control organic discoloration from natural décor like driftwood.

How does Fluval Stratum support planted aquarium growth?

The substrate’s porous granules create pockets where roots can easily grow and access trapped nutrients. Its structure also provides extensive surface area for beneficial nitrifying bacteria, which helps stabilize water chemistry and supports overall plant health.

• Porous, non-compacting granules allow root spread and oxygenation.
• Mineral composition supplies trace elements plants use to thrive.
• High surface area encourages rapid beneficial bacterial colonization.
• Works well with Fluval Plant Micronutrients for a complete nutrient profile.

Will this substrate affect aquarium water color or pH?

Fluval Stratum is formulated to avoid releasing color into the water, making it suitable when you use natural decorations like driftwood. It also helps maintain a neutral to slightly acidic pH range favored by many common aquatic plants and tropical species, without aggressive chemical shifts.

• Does not discolor water under normal use.
• Helps sustain neutral to slightly acidic pH favorable to plants and shrimp.
• Stable granules minimize compaction and chemical leaching.

How does this substrate help shrimp and small or newborn invertebrates?

The Stratum’s texture creates crevices and shallow shelters that newborn shrimp can hide in, reducing predation risk during vulnerable early stages. Its bacterial-friendly surface also contributes to a balanced micro-ecosystem that supports shrimp health indirectly.

• Provides refuge for baby shrimp and small invertebrates.
• Porosity supports beneficial microbes important for water quality.
• Granule size discourages compaction, keeping spaces open for juveniles.

How should I use Fluval Plant and Shrimp Stratum in my tank setup?

Layer the substrate to allow 1–3 inches for planted tanks, with deeper beds for root-heavy species. Combine with root tabs or Fluval Plant Micronutrients for long-term nutrient availability, and rinse lightly only if necessary to remove dust—over-rinsing can remove helpful surface microbes.

• Recommended depth: 1–3 inches for most planted setups.
• Pair with liquid or tab fertilizers for complete nutrition.
• Rinse sparingly to preserve beneficial bacteria coatings.
• Suitable for freshwater aquariums housing plants, shrimp, and tropical fish.

Who is this for: Aquarists who want a specialized substrate that encourages vigorous plant roots, supports beneficial bacterial colonies, and gives shrimp a safe start. Ideal for hobbyists setting up small to medium freshwater planted tanks, shrimp tanks, or community aquariums featuring delicate plants and tropical species. If you expect a long-term planted display or need a substrate that helps maintain gentle water chemistry without discoloration, Fluval Plant and Shrimp Stratum is a dependable choice.
