Very goood

The sand is a mixture of small shells and white sand. It looks very nice if thats what you’re looking for. The water does get cloudy after you first add the sand but this happens with pretty much any sand you get. It was well packaged with no leaks and came with a good amount of water in the bag for the bacteria.

Beautiful sand

This is gorgeous sand. I’m so happy with it. It has lots of shells and looks so pretty. I added it to a bare bottom QT tank and it went in super clean with no dust/clouding. Very happy.

Great combination

The combination of sand along with all the small shells and shell fragments produces a very pleasing and realistic look. It did not cloud the water very much and the Gobies love it. I really appreciated the fact that I didn't have to spend any time rinising the substrate before use. Hopefully, it does not contain an over abundance of silicates. I'm going to order more for another reef tank.

Looks like a Mini-Beach

This is the second time I've used this Live Sand setting up Marine Tanks and it's just BEAUTIFUL! White sand with lots of Small Shells and the Bacteria helps it through the Cycling Process. It truly looks like a Ocean Beach, both my Damselfish and Gobies love carrying it around and moving it!

Quite pretty

This live sand is a fine grain with small shells in it. It's very pretty and looks great in the tank. I have a new saltwater tank and it has helped cycle it quickly. It wasn't very dusty at all, had slightly cloudy water for only a couple hours. I would definitely order again if I ever need more. Much better quality than what I've seen in the stores for the price.
