Flourite is a unique gravel specifically designed for the planted aquarium. Essential nutrients are already in the gravel, so no supplements are needed It can be mixed with other gravel or used alone. For best results at least half of the substrate mixture should be of Flourite. Freshwater only.

The size and color of the gravel and substrates listed can vary due to natural availability and the resolution of your computer monitor.

For help selecting how much gravel you need for your aquarium, check our Aquarium Substrate Buying Guide.

Although pre-washed, it may be rinsed before use to remove residual dust. Dust can also be minimized by filling aquarium slowly and dispersing water so that the Flourite bed is not disturbed. Slight initial cloudiness is normal and will clear rapidly (2–12 hours). To shorten the cloudiness period use Seachem Clarity in conjuction with mechanical filtration (such as filter floss).

great substrate


Like most soil or nutrient rich substrate, it is very messy. Some people rinse the heck out of it, but this is just throwing money and nutrients. I use this as a base layer with pea gravel on top in my planted 75. Use a plate to diffuse water when filling tank. Cloudiness will go away in a few days. See it for yourself at stanjam.tumblr.com

Growing plants.


I have had aquariums for over 25 years.
I have a 110 gal. tank and its full of live plants and healthy fish. Start with flourite as a substrate, cover with sand or small gravel use a good filter and you lay the basics for the plants and fish to thrive. Correctly done tanks will thrive and need little care for years to come. Seachem has done the research. Read their info carefully and enjoy live plants in a tank that fish will thrive in.
