There is one thing you will find. The coarser gravel will find its way to the top. To keep it looking good you have to get rid of the gravel.  As far as I can see it will all have to come out, and be replaced by straight sand. I say that because in my tank even years after adding sugar sized sand there is still crushed coral coming to the top.
