Amazing!!!!. I order the Rock for my 180 Gallon Tank. I wanted a large amount. But was not sure. I ended up ordering my rock in two separate order of 5 boxes. In each box the rock was wrapped in Heavy Plastic and surrounded by foam peanuts. Took me by pleasant surprise. The rock is all that I expected and more. When I need more rock (I am already thinking of adding onto my aquascape - think it could use an arch- BRS and the Reef Safe Rock will be the way for me to go!!! Great Job folks.
