The Pleco problem may be related to the fish hitting puberty.  We had the 
same thing happen recently.  I'd look into backing off a little on your 
feeding anyway.  We also find that our pleco has less of a colon problem when 
we feed him boiled zuccini slices.  I'm not sure, but I think it may be more 
nutritious than what he gets from the tank bottom, so he passes less of it.
The snail shell problem is usually indicative of acidic water.
Good luck!
