can Aragonite be as a substrate for the big freshies such as arows, oscars, devils, bichirs,etc,? it does keep the pH stable if with a heavy bioload, and its has a number of times more surface are than gravel or sand, But supposedly its only good for africans and saltwater.

Yeah if your fish are already thriving in a alkaline PH then just go for aragonite.
Better yet, slowly add crushed corals.. The make good PH buffers.
