I have used bricks in the past. Never had any problem with the brick hurting the fish.
But I gotta say go with the landscaping place. I just took a buddy to one. He bought 68 pounds of rock for $6. .09 cents a pound since it was all small stuff and they classified it as miscellaneous rock.
Get some blocky stuff, some round river rocks and some flat pieces of slate. Done.

Thanks for the suggestions, i'll check out a rockyard.
