Pickling lime is a white powder, consisting of calcium hydroxide, chemically identical to commercially available aquarium hobbyist kalkwasser mix, although its MUCH cheaper. I would even go so far as to say that perhaps the germans (the pioneers of kalkwasser use) used pickling lime before many manufacturers got into the business of it, but thats just a guess on my part.
