Great to work with
The pieces are nicely shaped and easy to bust up into smaller ones if necessary with just a hammer's tap. Your imagination and aquarium epoxy is the only thing you need now to make some interesting shapes.

Great product
We were very skeptical purchasing this product, based on the reviews, but we tried it anyways. We have purchased a few times and every time we have been more than satisfied. The box seems to contain more than the advertised 5 lbs. There is a nice selection of big and small pieces, fitting for building towers and productive landscapes. Just ordered another 2 boxes. The price is right. Rinse it well, there is dust due to shipping. It is a good product. Thanks.

Great Rocks!
Bought 5lbs to try in my Fluval 13.5 tank loved them so much bought 10lbs more. 5lb box was packaged with extra care causing minimal breaking during delivery. I only wish the same care was used to package the 10lb box but I was still happy with the contents.

Good Product
Added to my existing rock scape. This is a great value for base rock or adding flats for corals. I made some sick scapes on the table with this before throwing it in with what I already had. Only thing is the scapes looked very unnatural. Might need to chisel some edges after building with it if that bothers you.

Small pieces
Very small pieces. I have a 200 gallon tank and I'd rather have two big pieces than 10 tiny crumbs.

Arrives with much rock broken into small pieces or rubble.
Received my two little fishes stax rock today, this will be my 3rd reef tank I have set up in 5 years and always order dry rock. First impressions is yes this will be very easy to stack and make amazing aquascapes with. I really wanted to love this product, but after reading reviews in many places was skeptical about ordering so I ordered a 5lb box to see how it arrived. I took the 2 or 3 largest pieces out and weighed the remaining on my baking scale and over 1.5 lbs of rock that were smaller than 1/2 of a dollar bill with much of it being rubble that I'll throw in my sump. At the price that this dry rock sells for I could have bought premium live rock with free delivery. I have always used dry rock at half the price of this rock. And the company I am going to end up ordering from bubble wraps each piece separately so you don't get breakage, has free shipping and is only $2.99 a pound. I will say that the rocks that made it through shipping without breaking are great and I wish I felt confident enough to order another 40lbs of this rock but sadly I don't. Please Two little fishes figure this out before I start building my 120 gallon reefer, I would love to use just your rock. In the meantime I'll use what I have received for a stable base in my 32 gal biocube.

Yep, they’re rocks!
Works exactly great for my aquascapes, bought, easy to count on a dim and saw or simply break into a random piece to work with.
