Beautiful assortment
Great value for the money. Most aquatic stores will charge $6 a pound for these. Make my tank look natural.

Very Dirty and the rocks were black
They were really black look like coal not like Grey rocks. Cleaned up ok but the package was so filthy and we had to wash the rocks ASAP so it didn’t get everywhere.

Not what to expect
I get that there rocks but I donât understand how they send 5lb instead of ten I was pretty pissed off even tho I can just go out side and get some but these âlooked like cool shaped rocksâ feeling ripped off

Gorgeous rocks
I order 2 packages of these rocks and am very pleased with them. Their color is charcoal, almost black, but they have veins of white quartz (I think?) through them, so their texture is wonderful. Paired with a light color sand with scatter stones that match the rocks, the tank is turning out beautifully. I intend to order another box, though. 2 wasn’t enough for the 55g tank I’m setting up.

These are beautiful!
I love the way these look! I added them to my new 75 gallon saltwater tank, and they look great along side the red colored live rock! Great contrast! I’ll be adding coral, plants and then fish next.

Good quality rocks.
Christine Gosau –
Sehen super aus. Im Aquarium auch nochmal besser. Wirklich sehr schön und absolut zu empfehlen. Wichtig ist, dass man sie vorher einmal wäscht, damit man evtl. Verschmutzung nicht im Aquarium hat. Aber ich denke, das versteht sich von selbst.
