Seachem Flourite Sand
Seachem Flourite Sand is designed specifically for use in freshwater planted aquariums. The fractured stable porous clay gravel is most effective when used alone, but can also be safely mixed with other gravels for additional aesthetic designs. The Seachem Flourite Sand is not chemically coated or treated, will not alter the pH balance of the water, and does not need to be replaced as it is good for the life of the aquarium. Mechanical filtration will help to remove any residual cloudiness from the product.

I’ve used Flourite Sand in my planted tank for over a year. The roots grow well, and the water stays clear. No pH changes, and the substrate feels stable. Works perfectly with my live plants and filter setup.

The sand is easy to work with and doesn’t cloud the water. My aquarium has been thriving since I switched from regular gravel. No maintenance needed, and the plants are healthy.

It’s a solid choice for planted tanks. The porous texture helps with root development. I mixed it with a little fine gravel for visual appeal, and it holds up well.

I didn’t expect it to be so stable. After a few months, I still haven’t had to clean or replace it. The plants are growing strong, and the water clarity is excellent.
