He replaced the tank itself, so he removed all gravel, and Live rock from the tank, and swapped it to a new tank.
My questions:
a) did you distirb your "wet dry" filter.
b) Do you Have dead coral, meaning ones you "bleach" to keep white, or would you consider your rock "live rock".
c) Did you remove the sediment from your gravel/sand when you moved it? Or did you simply scoop it from one tank to the other "including" the sediment. (either gravel vac, or rince it in tank water?)
