Laterite supplies mostly iron, and I don't think very much of that would
become available to the plants if the laterite were on top of the gravel.
Some people advocate shoving balls of clay under the gravel.  I think that
additions of chelated iron couldy supply what the plants need.  Save the
laterite until the next time you set up a tank.
