I have 2 Cool Surge cooler/heaters that I think I bought in 2009. I need some
new 3 1/2 x 5 1/2" x 1" ice blocks. Where can I get them?

First, construct a watertight box whose inner dimensions are 3.5" x 5.5" x 1".
Marine-grade plywood should suffice; caulk the seams.

Fill with water and freeze.

Won't work. She needs 3 1/2 x 5 1/2, not 3.5 x 5.5. You need a special
ruler to make that.

Dang, you caught me. I want the U.S. to switch to the metric system.
