I would have suggested it had I known you were using a tub! XD

Yep, more holes. I know some people who have like 200 holes in a tub.

BTW, your thermostat probe should be on the outside of the tub directly taped to the UTH and your thermometer probe should be inside the tub directly on the plastic where the UTH is (under the newspaper).
