Beautiful, fake rock!
Size: 40-Pound
I saw in the review that someone was complaining that it wasn’t live rock… it is not it’s better! Also heard complaints about breakage and shipment… I’m really not surprised, but delivery just dropped it on my driveway so hard that I could hear it from inside the house… only one little piece was broken. I was so shocked each individual peice were wrapped well! The last time that I ordered it, I did have some breakage, but it glued back together easily with super glue or frag glue and it’s lasted for years. The shapes in this package is nice mix of shapes makes easy to work with holes and arches for critter homes! The stuff is beautiful and I have used it in my tank since it came out years ago… the purple holds its color and really looks like Coraline algae! Grows corals and algae just like the real thing! Without all the hitchhikers that come with live rock. Make sure it caribsea life rock! I did try and off namebrand It was like plaster and just broke apartin a few months ... show more

Y shaped branch rocks. Man made and DRY ROCK
Size: 20-Pound
The media could not be loaded. I love the color and the composition of the rocks. I didn't like having to fix all the broken branches from shipping. Adequately padding packaging and a better assortment of shapes would be recommended but overall it is a good product. These are dry and are man-made. The title is a little misleading to newer aquarium owners. In the video The flat rock is “macro”, boulders are “reel reef” rock, “reel reef” fancy reef rock is the pointy style and the Y shaped “Caribbean” sticks are the ones I got on Amazon. ... show more

These helped make my salt water tank beautiful. These came and there were a couple broken rocks in it but honestly it was okay because it helped make it to where i could build more for my fish to swim around it

The media could not be loaded. Overall, I am SUPER happy with this purchase! There was a large variety of sizes and shapes in my box, all with lots of nooks and crannies which will be great for future inhabitants! I will say that several pieces had chunks broken off them from shipping, but considering the volume and weight of this package, it doesn’t surprise me. I can’t complain. The rocks still look great in my tank. I already had a decent bit of rock in my 55 gallon newly set up tank, as I transferred some live rock to it from my 32 gallon Biocube. So not all of this shown in my tank is from my shipment. That being said, I had four pieces leftover after arranging in my 55 gallon tank, one of which was very large, and I put those four into my biocube. The rock shown laid out on the table on the newspaper all came in my order. Beautifully colored pieces! ... show more

The rocks are amazing heavy plenty. I was worried about if it was going to be enough since I was only on pounds versus the quantity only complaint I have which I don’t think it would be with the company in which I bought from maybe the Amazon delivery is that there were a lot of them Broken Although they were all wrapped individually. There’s plenty of holes for hide and spots. I was able Use a broken piece to make a bridge so I definitely will recommend them. Thanks. ... show more
