After redoing my rockwork again (weekly event) I have decided that what detracts from my tank/corals/scaping is the blue background. I want to remove the blue from the back of my tank, but the problem is that it's full of water. I guess the best way is a razor blade and a vacuum? Also, I know there is some kind of black adhesive that looks REALLY good as a background. Anyone know where I can find it in SA? I know one of the retailers (RCA?) carries it, but I'd like to know what the name of it is so I can try to track it down here in SA.
