Yes to the question on plants not needing special soil. But I would not mix sand and gravel, as the two will mix together and the sand will be on the bottom and gravel on top. I would also use only one substrate, my personal preference is small grain gravel, grain size about 1-2 mm, in a dark or natural colour. This works best for plants and bacterial activity essential in the substrate. Many do use sand, but it is more likely to compact (the deeper the more it compacts).
