I bought some of the premium live rock from K. P to jump start a 150 gal reef tank I am making. Local stores in my area don’t have this type of product . They were on top of my small order from the beginning to the end , the rock came and it was awesome, all kinds of life you could only get from rock that’s been in the ocean for a while. The only bummer is now I look at just my rocks every day while my tank cycles, but I get my flashlight out and I am amazed at all the life on the new rock. Would for sure recommend.
