What is the smell you speak of? I have not dove there but would like to try out my drysuit for a bunch of shake down dives and I live not to far from the place.
 
I have never dove this site (Hudson Grotto) but I have done Hospital Hole (similar location). There is a sulfer layer that smells something like rotten eggs. There was also a rumor that if you have a weak stomach it may make you puke. I dont think it is that awful, but it will leave your gear smelling foul.
 
It's not too bad, but yes - hydrogen sulfide - rotten eggs. I could actually taste it in Hospital Hole. I didn't think the Grotto was that bad. I only smelled it once I was home and in the shower. I think people equate the tanic water to bad/low viz. But the viz is actually pretty good. Below 45-50ft it becomes a night dive though - no light from the surface - so make sure you've got a good light.
