I had a hammer coral suffer RTN last week which I suspect was initiated due to my own clumsiness hunting a crab (!). Iodine dips etc couldn't save it unfortunately and it was removed from the tank 4 days ago.
Short question is, should I do anything to my tank before introducing a replacement? (Is the water contaminated?)
