Seachem Flourite
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® works best when used as a standalone substrate, though it can be mixed with other gravels. No gravel modifiers like laterite are required. The product is not chemically coated or treated and will not affect water pH. It is durable and does not need to be replaced during the aquarium’s life.
Set-up
Although pre-washed, Flourite® may produce dust during transit. Rinse the gravel 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. The roots grow well, and the substrate stays stable. No pH changes, and the fish seem healthy. Easy to rinse and set up. No need to add any modifiers. Very satisfied.

The gravel looks natural and fits well with my live plants. I didn’t need to add laterite or any other substrate enhancer. It holds nutrients well and the water clarity has improved.

Great for beginners and experienced aquarists alike. The porous structure supports plant growth. I’ve kept it in my tank for 18 months with no issues. No dust after rinsing, and the tank looks clean and natural.
