I recently switched to Seachem Fluorite Onyx Sand for my aquarium, and it's been fantastic. The 7 lb bag was just the right amount for my 20-gallon tank. The dark color really makes the plants pop!

Great for cichlids!
I bought the Seachem Fluorite Onyx Sand for my cichlid setup, and it works well. The sand is easy to work with, and the fish seem to love it. Just be careful with how much you add; it's heavier than it looks!

Not what I expected
The sand was a bit more coarse than I thought it would be. I was looking for something finer for my shrimp tank. It still looks nice, but it wasn’t the right fit for my needs. Delivery was quick, though!

Good but a bit dusty
While I love the color of this substrate, it was a bit dusty when I first opened the bag. After rinsing it thoroughly, it looks great in my tank. Just wish it was cleaner out of the package!
