Carib Sea Arag-Alive Substrate, Bahamas Oolite, 20 lb.

great product I liked

Sand looks amazing.

This black sand has made our saltwater aquarium so beautiful! It changed the looks of it from the white sand we had. The aquarium has now cycled and we have added only one fish to make sure. I can't wait to get the rest in there and add more!

Looks nice, the picture makes it look 50/50 black with white, it's about 80/20 mostly black. Looks nice, doesn't get shot around by powerheads. The grains are similar to that of rock/cane sugar. I highly doubt this did anything for my cycle, still took about a month. But my hitchhikers are just thriving inside if it.

Used in my nuvo 20. Have a ecotech mp10 with quiet drive set decently high and this sand still stays in place. The granules are big enough to not blow around, but still small enough for my conches to sift through.
