DESCRIPTION

Iron, manganese, and sulfur walk into a greensand filter. Pot Perm walks them out.

Pot Perm Plus is the potassium permanganate your greensand iron filter runs on. It oxidizes iron, manganese, and sulfur so the filter can trap them, which means no more rust stains and no more rotten egg smell.

Each case has 12 bottles at 1.75 lbs, so 21 lbs total. That’s about a year of clean water for most homes, depending on your water quality.

For greensand iron filters only.

HOW TO USE

Easy refills. Zero guesswork.

  1. Add one bottle (1.75 lbs) to your pot perm tank. Never add more than one at a time.
  2. Let your filter do its thing. Each regeneration uses 3 oz, and it should run at least every 4 days.
  3. Check the tank water. If it fades to light pink, add another bottle.
  4. Expect about 9 regenerations per bottle. That’s roughly one bottle a month, or one case a year.
HOW DOES IT WORK

Greensand catches iron. Pot Perm keeps greensand ready to catch more.

Dissolved iron, manganese, and sulfur slip right through a plain filter. Here’s how Pot Perm stops them:

  • Oxidize: During each regeneration, potassium permanganate recharges the greensand. The media then turns iron, manganese, and sulfur into solid particles.
  • Trap: The greensand filters those particles out of your water.
  • Flush: The next backwash sends them down the drain.

Clear water out. Rust, black stains, and egg smell stay behind.

How Much, How Often

  • Use 3 oz per regeneration cycle
  • Never add more than one bottle at a time
  • Your pot perm tank should regenerate at least once every 4 days
  • Refill when the solution turns light pink — that's your cue
  • One bottle typically covers about 9 regenerations
  • One bottle a month is roughly typical usage — meaning a 12-bottle case lasts about a year for most households
