Details

This aquarium substrate has fairly uniform 1/4 to 1/2 mm spherical or egg-shaped grains for reef and marine aquaria. The grains are aragonite, a naturally occurring calcium carbonate material made in the shells of many marine organisms. It has a superior buffering capacity to keep pH stable in a range suitable for most marine aquariums.

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.

Dirty sand

by

This sand was extremely dusty and had a lot of foreign debris. I had to wash it about 20 times to get the dust down to reasonable levels before adding to my tank.

Very nice after a thorough rinse

by

It is dusty, but they admit that on their site. Once cleaned it looked amazing in my yellow top Mbamba breeding colony. Even after cleaning, it took a few days to settle. I’d buy it again because the finished product was exactly what I was looking for.

DUSTY - HORRIBLE

by

Absolutely horrible sand. Dusty, and clouds the aquarium to a severe degree. Any movement will bring up dust and there's almost an inch just sitting in the bottom of my filter system. It's ridiculous. I'm getting new sand immediately.
