dont buy from liveaquaria.com unless you never plan on seeing the rock in the tank. i bought 20 lbs of their figi premium and it looks disgusting. the rock is very brown and black, and has little to no coraline algea, not only that but it has absolutly no hitchikers. i havn't found a single thing come off that rock. this rock looks so bad that ive decided to take it out of my aquarium and place it in the fuge so ill never have to see it again
