Seachem Flourite Black 15.4 lb Planted Aquarium Substrate
Seachem Flourite Black 15.4 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.
Flourite Black can be used by itself as the main aquarium substrate or mixed with other planted tank substrates. Because it is stable and long-lasting, it does not soften, decompose, or need to be replaced over time like some organic aquarium substrates.
