A word of warning - it's very difficult to get all the laterite washed
out of the gravel.  I tried this when I redid our 100g tank a year
ago.  I washed it all, then mixed new laterite in the lower 1/3.  The
problem was that the top 2/3 still had enough laterite to cloud the
water for two weeks.  Unlike my usual experience with Dupla laterite, 
it didn't seem to settle out this time. 

Save yourself a lot of trouble and get new gravel for the top layer.
