At just about any store that sells swamp cooler parts, you should find
"algae blocks". I can think of one called the Fresh Air Block. These are
simply placed in the pan, under the inlet water flow, and allowed to
disolve. You might have to check on them monthly depending on your cooler
usage.

also set up a bleed hose that a small amount of the water that is
pumped to the pads is dumped out ...use it for the lawn or
whatever....this keeps the water from building up a large concentration
of minerals and other junk....
