Interesting. I know copper is used in boat bottom paint because it's

how would having copper tubing in the coils kill slime? Zinc is used on
roofs with problems to keep algae from growing. If you drive around here,
you can see roofs where there is no algae on the roofs below flashings,
vents, etc that are made of zinc.

come out with lead pills to deal with copper
