Transform your aquascape with the ultimate foundation for lush, vibrant live aquatic plants. Seachem Flourite is a specially fractured, stable porous clay gravel designed specifically for natural planted aquariums. Unlike cheap alternatives, it never breaks down, becomes muddy, or needs to be replaced—making it a lifetime investment for your tank.
Whether you are a beginner setting up your first low-tech tank or an expert aquascaping a high-tech setup with heavy root-feeders like Amazon Swords and Crypts, Seachem Flourite provides the structural and nutritional support your plants crave.
Why Choose Seachem Flourite?
All-Natural & Unaltered Chemistry: Flourite is completely organic and chemical-free. It will not alter your water pH or water hardness, ensuring a stable environment for your fish, shrimp, and delicate aquatic plants.
Rich in Essential Micro-Nutrients: This premium substrate is naturally packed with iron and vital minerals, encouraging strong, healthy root development right from the start.
High CEC (Cation Exchange Capacity): Flourite acts like a nutrient magnet. Its porous structure absorbs liquid fertilizers and fish waste nutrients from the water column and holds them right where the roots can easily absorb them.
Lifetime Durability: Unlike standard aquasoils that disintegrate into mud over 1 to 2 years, Flourite stays crisp and structural for the entire lifespan of your aquarium.
How to Use Seachem Flourite
For best results, you can use Seachem Flourite as a standalone substrate bed, or mix it with other gravels.
Pro Tip for Crystal Clear Water: Because it is a natural clay product, Flourite contains dust from shipping friction. Always rinse it thoroughly in a bucket with a garden hose or siphon before adding it to your tank. When filling your tank, pour water over a small plate or plastic bag placed on the substrate to prevent disturbing the bed.

SET-UP:
Although it is pre-washed, because Flourite is a natural product, it may become dusty in transit and require rinsing before use to remove any residual dust.
When adding water to aquarium, fill slowly to avoid disturbing Flourite substrate bed. Place a bowl in the aquarium and add water directly to the bowl, allowing water to overflow softly on to the gravel bed. Initial cloudiness is normal. To remove cloudiness, use mechanical filtration (such as filter floss). Use Clarity to accelerate clearing.
