You can do it one of two ways.

1) For a short bath, i put the water at 92, then in about 10 to 15 minutes it hits around 80, and I usually take him out then.

2) For a long bath I put the water at 92, then I put a facecloth in with him (if it is becuase of a bad shed) and i put a temp probe in their and then a lid, put it in the tank on top of the heaat pad with a heat lamp above and you can moitor the temp and leave him in their for up to 45 minutes I would say.
