+1 mng. Is the OP testing for strontium? Probably not.
As for the shrooms, IME they tend to take a while to split. THe guy at the store might have been full of poop. They split from the base mostly. You'll see the "root" look like its spreading and a day or 2 later, you have a new shroom. Also, when they're expanded really big, they're in lower light. When I put mine at the bottom of my tank under halides, they shrank to almost nothing. When I moved them into the shade, they expanded again.
