Amazing dry rock.
I was looking rock to aquascape with and this is the best deal I could find. Yes the order does come with 2-3 rather large pieces and 1-2 smaller size pieces to fill the 40lb mark. Picked up a $5 chisel and $20 of glue/activator and got to work. If you don’t want to put in the effort to build your own aquascape all you need is a $5 chisel and a household hammer. The rocks have natural openings/weak spots and it’s easy to break them into reasonable size pieces with a little effort. The smaller bits are perfect for the refugium. Note in the picture I did have one base piece to start but I also had a leftover 1-2lb rock and multiple fragments for future projects.
Not as described
The reviews and pictures show a group of smaller-medium sized rocks adding up to 40lbs. I recieved my order today its 3 massive ugly rocks. Don't waste your money or time buying this product.
Good value!
This rock was a really good value. I wanted to create my own aquascape and needed rock I could break into unique shapes. Customers should understand that this comes in 2-3 huge chunks of rock. You will need to break this rock up some if you don't want huge boulders in your tank. However, this rock was REALLY hard to break. I was able to use a hammer and chisel to get some chunks off but understand, it takes alot of work. Overall, great value for the money.
One Rock in the Box
I sent one rock and it weighed 4.5 lbs. The picture showed multiple rocks and said forty pounds. I got one rock! The rock is really nice, wish there were 40lbs.
perfect addition
Arrived as described. 2 large rocks. Perfect for large tank.
Be aware when buying
For a 40lb box, we expected several rocks, however, there were only 3 massive rocks that do not fit our tank.
