Is cement safe in an aquarium?

  • We are currently upgrading MFK. thanks! -neo
I see no reason why it isn't if you use cement for ponds as well.
 
I used quickrete mortar mix to construct my tank's back groud inside the tank. It is safe.

You just need to cure it for a long time before you put any fish in it.
