As dumb as a box of rocks!
I needed to find the right rocks for my planned scape. I knew the ones I wanted, but I can't tell you what they are called, as I am no geologist! They are dark grey with white lines running through them.
Anyway, where I am working there is a big lake, and a few years ago they built a dam wall to increase the size of the lake. This dam wall has been protected from erosion by the use of tons of the exact rock I wanted. I am not about to advocate the theft of rocks from dams, but there must be a million tons there(slight exaggeration!), so my removing 25 kg for my tank shouldn't effect the structural integrity of the dam!
