I know! I know!

Cal-hypo pellets!

We have a well drilled into a "sulfur vein", common in this part of Pennsylvania. What that means, in practice, is that the well water contains sulfur producing bacteria which are harmless but exceedingly stinky. Think rotten eggs. We treat the raw well water with an apparatus which injects a chlorine mist into it and then filters that out via a carbon filter.

About once every other year when the equipment fails due to corrosion of parts from the chlorine we have to shock the well.You do that by dropping chlorine pellets directly into the well. The amount depends on the depth of water in the well; you're shooting for 5 ppm for shock level. People who use pellets to sanitize their wells on a daily basis maintain somewhere between 0.6 to 3 ppm.

The pellets are 3/8" in diameter x 5/16" long and weigh 1 g each. 70% cal-hypo.

Aren't you glad you asked?
