You could save your self some money by buying a breeze-block in the UK rather than paying loads for shipping a block of concrete from Germany.
Also this thing looks like plain concrete to me so it I don't think it will hold alot of water so, unless it in inside a humid tank, you can only realy keep desert and some Southern-European spec. in it. A breeze-block however holds lots of humidity so you can use it for almost anything.
