Blackadder Posted November 22, 2006 Report Share Posted November 22, 2006 I'm thinking about making rocks and caves for a Malawi tank and I'm wondering if anybody has done this and how sucessfully it went. I've looked on the net and found some stuff about coating polystyrene with cement, so I was thinking of trying this, but I was wondering if the oxides you can get to color the cement are toxic to fish. Also has anyone tried acid washing the cement after its dried so you can use it in the tank quicker or do you just have to soak it for ages? Are there any other good ways of making rocks and caves?
