View Full Version : Red-clawed Crabs and aragonite

I am currently setting up a brackish tank for red-clawed crabs. What I've read so far shows they like the PH a little higher. With this in mind, could I use aragonite as a substrate? I already have some, and if it can be used, it saves me from having to go buy something else.
