I bought these to use as the bottom layer of my substrate. The description is very accurate, I received the number of pieces stated and about a pound and half over. I gave them a good cleaning. They didn't seem that dirty to begin with, which was nice. I got a variety of sizes that matched the size description. They have a nice color once wet. I liked the varying textures and shapes provided. The largest stone would make for a great centerpiece and I might save it for later.

I bought two orders of these for my new 75g aquarium and would love to give them a solid 4 stars, but 3 of my largest rocks would NOT sink! Unfortunately it wasn't until I added water that I discovered this. So, be prepared to either test the sinkability of each rock before you set up your hardscape, or glue everything in place before adding water. I tried for weeks to get them to sink with no success, drilled tons of holes in them, soaked them for more than a week, I mean these things are bouyant! Lol Other than the three I wasn't able to use the rest look great, and overall I'm happy with the purchase. I do feel that if you're selling something for aquarium use it should be tested before it's sold to make sure it will actually stay in an aquarium without a bunch of extra work.
