bad sheds will happen, nothing you can do about it .. I have 1 tub free just to fix this .. i put about 6 paper towels one on top of the other and pour water in there - not too much though, you don't want a pool of water in there .. I move the snake that shed badly in there and in an hour or so she will peel off the dead scales .. then I move her back to her tubworked every time for me
