Never tried gnat nix and reviews are mixed.

Not sure how it's different than perlite, which is also puffed glass.
Probably works like sand -- it smothers the top layer of soil. The problem with sand is that it eventually gets watered in and becomes less effective. If you can bottom-feed, a thick layer of sand is a cheap and effective way to get rid of fungus gnats.
