Hi All
I am working on my aquascape and most of the Marshall island rock has orangy brown color throughout and I am concerned it is rust from some natural metal inside. Initially i thought some of it was sponges but it is rock solid. I feel its some rustical or something that may cause issues. I have decided I am not going to use majority of the pieces but few of the larger pieces I need to achieve the aquascape I am going for.
Has anyone seen this and is it safe?
