The two products are basically the same and very good for live plants. Just wondering, why did you put Flourite under Onyx Sand?
For me, I used them separately...
Some prefer laterite (clay-like), then putting gravel on top of laterite to keep it down and not in the water column. I chose not to use laterite due to the possibility of "turning over" the laterite.. SeaChem's Flourite and Onyx Sand simplify things by not having to mess with the potential of disturbing the laterite.
