I did not know that. I have seen some talk about this but it was never in much detail and most was for fish tanks and getting the water back to normal before adding fish. So what should I use on a foam background fixed in the enclosure that can not be submerged? It seems that some just cover a foam background in quikcrete, seal it and that's it.
