Hi , does anyone know a safe acrylic resin that can be used in marine tanks, I have taken some really good latex moulds from tufa rock and now want to join these together and make a 4 foot long rock wall for the back of my tank. I was planning to make it about 2 inches thick (not including the lumps ) , and crush some tufa rock to dust to line the mould before the resin goes in. then when its set the surface will look and feel like real tufa, but i will have a solid sheet 4 ft by 2 ft. can anyone help
