Pro Products KP02N Pot Perm Plus Greensand Iron Filter Regenerant (3 Pack) - Water Softener System Treatment for Well, Iron & Manganese Removal - Home & Commercial Use

works for purpose but if you can get it from a water salt place you get more for more for moneyWe use with our water filter system! Works perfectly! Great find!I know that this product works in my system, but the description does not list the size, volume or weight of the contents in each bottle. I received the three bottles as noted, but they were MUCH smaller than the bottle I had purchased previously. Poor description and, unless you know how to use it, poor instructions on how or where to fill a water softener. Considering the small size of these bottles and no instructions on how much to use, this item is over priced and poorly labeled.Fifth year using this great Pro Perm formula in iron regeneration tank.1 - 28 bottle lasts 6 months providing iron free water.Live in FL woods where our well water has high iron content.Very pleased & appreciate Pro Perm’spromptly shipping the product.a little slow arrivingNo seal bottles.
