Calcium chloride (high-grade ice melt) will melt stuff very
well.  Unlike rock salt it generates significant heat as it dissolves
-- I tried to make a saturated solution once and it got up to
185F.  That's why it's no good for ice cream.  So use lots but keep
an eye on the solution temperature.

Or else the pump is broken.  The submersible pump will burst if water
freezes inside it, and I'm pretty sure the cabinet-mounted one will too.

Yrs,
