Gravel as well as sand is suitable for the pond floor or plant substrate. When deciding be aware that sand silts up sooner than gravel. On the other hand with fine gravel the sinking rotting material settles in the cavities, which makes cleaning more difficult (a sludge vacuum is useful in this situation).
