Incredible rock. Shipped in water is the way to go. I ordered 125 pounds of Aqua cultured live rock shipped in water. The freight was quite a bit more but worth it. I cycled my new 240 gal with this. It cycled in 6 days. Did 3, 60 gallon water changes and lost nothing on the rock. After 6 days ammonia zero. Shipped in water is the way to go! I just added another 80 pounds. Zero ammonia. The rock is exactly as pictured with lots of life.
