Profile does not disintegrate in water. It is truly a superior substrate IMO, the only problem being it's weight, or rather, lack of it. Put the gravel on top (i.e. as a cap). Things tend to mix up, moreso when you do a lot of replanting, but it's not really a problem. Just to round things out, I have used Profile by itself and it always does well for me, but it was in a tank with minimal water circulation and no digging fauna. Even then, water changes were a bit of a pain, and I always lost some out the siphon.
