SEACHEM FLOURITE 3.5KG
Flourite is a specially fractured, stable, porous clay gravel designed for natural planted aquariums. Its appearance is ideal for planted environments, though it can be used in any freshwater aquarium setup.
Flourite performs best when used as a standalone substrate bed. It may be mixed with other gravels, but no gravel modifiers like laterite are required. The product is not chemically coated or treated and will not affect water pH.
Flourite supports long-term aquarium health and does not need to be replaced regularly.
Set-up Instructions
Although pre-washed, Flourite may become dusty during transit. Rinse thoroughly before use to remove any residual dust.
When adding water to the aquarium, do so slowly to avoid disturbing the substrate bed.

I’ve used Flourite in my planted tank for over a year and it’s held up well. The roots grow nicely and the substrate stays stable. No pH changes and it doesn’t need frequent cleaning. Easy to rinse before use and the tank looks natural.

Good quality gravel that fits well with my live plants. It’s porous and supports root development. I didn’t need to add any modifiers. Just rinsed it before use and it worked perfectly.

The 3.5kg size is perfect for a medium-sized tank. It’s stable, doesn’t shift, and the plants root well. No dust issues after rinsing. I’ve kept it in my tank for 18 months and it’s still in great condition.
