I bought some Ocean Wonders frag tiles and put them in my frag tank 2 days ago. I took one out tonight to trim some birdnest up to put on plugs. The whole frag popped off the tile and there was this orange residue that seems stained on the tile. This orange was not on the superglue or coral.
Is this normal? Should I remove all of them from my tank?
