Seachem Flourite Black 7.7 lb Planted Aquarium Substrate
Seachem Flourite Black is a premium porous clay gravel substrate designed for freshwater planted aquariums. Its rich black color creates bold contrast with live plants, colorful fish, shrimp, rocks, and driftwood while providing a long-lasting base for aquascaping and root-feeding plants.

For demanding plants or heavy root feeders, Flourite Black works best when paired with root tabs, liquid fertilizers, proper lighting, and regular aquarium maintenance.
Usage Tips
- Rinse thoroughly before use to help reduce 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.
