Greensand filters are an effective way to remove iron,manganese,and hydrogen sulfide from your water. Greensand is actually a mineral called glauconite,and when it's coated in manganese oxide,it can oxidize the iron and other contaminants,allowing them to be filtered out. This type of filter needs to be regenerated regularly with Pro Pot Perm or a similar agent,however,or it won't be able to work correctly. Find the regenerants you need at US Water Systems.
Pro-Pot Perm regenerates and oxidizes greens and iron filter media - Case of 6
Typically,the compound potassium permanganate is used in the regeneration process. Often abbreviated as "pot perm," this compound is a strong oxidizing agent and very effective at adding oxygen to the greensand and removing any built up iron or other contaminants.
Pro Chemicals provides several unique blends of potassium permanganate greensand filter regenerants designed to add oxygen and rid the filter of iron and other minerals. These blends are powerful oxidants that are also effective for use when filtering manganese or hydrogen sulfide. Pro Pot Perm is effective for both Manganese Greensand and Greensand Plus medias.
