i just bought some for a friends nano tank and it is the most amazing rock i have ever seen. as lame as that sounds it was. there were thousands of healthy barnicals, sponges,and full sized large crabs. along with micro algie as well. i will be buying all my sand and rock from this place. eco frendly and so much better than other chizzled live rock. it looked like the ecosystem was complete after just the rock. no chizzling and 10 times better
