Seachem Flourite is fantastic for growing plants in a freshwater aquarium and the black color REALLY makes fish colors pop. Only thing to watch out for is how dusty the sand is out of the bag. Spend some time washing it before adding it to the aquarium or just give it a few days for the fine particles to settle.
The planted gravel/sand I purchased worked well and is visually nice. It did take about 2 days for the particles to die down enough to have clear water however even with a new filter system on the tank. Overall I’m pleased.
