Seachem Flourite Dark 15.4 lb Planted Aquarium Substrate
Seachem Flourite Dark is a premium natural clay gravel substrate designed specifically for freshwater planted aquariums. Its rich dark color creates beautiful contrast against green and red aquatic plants while helping colorful fish, shrimp, rocks, and driftwood stand out in aquascaped tanks.

Plant Benefits
Seachem Flourite Dark provides a stable porous structure that helps rooted aquarium plants anchor securely. It is useful for planted aquariums featuring crypts, swords, vallisneria, stem plants, foreground plants, and other root-feeding species.
For demanding plants or heavy root feeders, Flourite Dark works best when paired with root tabs, liquid fertilizers, proper lighting, and regular aquarium maintenance.
Usage Tips
- Rinse gently before use to help reduce dust and initial cloudiness.
- Add water slowly over a plate, bowl, or plastic bag to avoid disturbing the substrate.
- Use a deeper layer in areas where heavy planting is planned.
- Pair with root tabs or liquid fertilizers for nutrient-demanding plants.
- Allow filtration to clear any remaining fine particles after setup.
Coverage Guide
Coverage will vary based on tank dimensions, desired substrate depth, and aquascaping style. A 15.4 lb bag is useful for small to medium planted aquariums, deeper planting areas, or accent sections in larger aquascapes.
For larger tanks or deeper substrate beds, multiple bags may be needed.
