Pot Perm tank for Rainfresh and other Greensand filters.

Pot Perm Tank Feeder Assembly incorporates a non-pressurized storage tank and innovative grid design along with a dependable float valve. The attractive 10”x16” tank is made of tough blow molded high density polyethylene, and contains an ultraviolet inhibitor (UVI) for increased resistance to sunlight.* It has a storage capacity of up to 30 pounds of Dry Weight Potassium Permanganate. See the Dosage and Fluid Requirements chart located on the back page.

The black injection molded cover is securely fastened with two stainless steel safety screws to prevent access by children and pets. The fill port on the cover also includes a child resistant closure. (As with all chemicals, the potassium permanganate  chemical tank should be placed safely away from children or pets). Chemical warning and drain caution labels are affixed to the unit.

The unique polypropylene felt grid pad in the pot perm tank retains even the finest grade of undissolved  potassium Permanganate above the grid. This permits efficient use of our assembly with all grades of Potassium Permanganate. Two and four ounce feeders have a grid platform height of 5 inches. Six ounce feeders have a grid plat-form height of 71⁄2 inches. The unit is shipped fully tested and assembled in individual cartons. Shipping weight is seven pounds. Please consult the factory for further information.

The recommended dose of Potassium Permanganate for regeneration of MTM® or Manganese Greensand is 11⁄2 – 2 ounces per cubic foot. For Greensand Plus™ please refer to the manufacturer’s data sheet. Correct water temperature is important to properly dissolve Potassium Permanganate. At 50°F (10°C) four ounces of Potassium Permanganate can dissolve in one gallon of water. At room temperatures (72°F – 22°C) eight ounces will dissolve in one gallon of water. For further information
