I've had a tank setup with profile for over 4 years now.  I've never experienced any problems with it.

The Profile I used was labeled as an aquatic plant soil for use in ponds.  The guy I bought it from
thought I was crazy.  He asked me how my pond was doing, and I told him, "I don't have a pond, I'm
going to use this in an aquarium".

My point is, if in fact it's leaching nitrates, it can't be used in ponds either.  I would return it
and try to get more from a different lot number.
