The pH level of your water source must be between 6.2 and 8.5 or it will not work
It must be regenerated with potassium permanganate and backwashed often to prevent clogging.
Also, the amount required depends on your level of iron or hydrogen sulfide
Typical 9 x 48 tanks uses 1.0 cu.ft. ( Order 2
bags of Greensand Plus )
and 10 x 54 tank uses 1.5 cu.ft ( Order 3
bags of Greensand Plus )., and don't forgot to order Gravel too.
The manganese dioxide coated surface of GreensandPlus promotes the oxidation reaction of iron, manganese, and hydrogen sulfide.The silica sand core of GreensandPlus allows it to withstand operating conditions in waters that are low in silica, TDS and hardness.GreensandPlus is effective at higher operating temperatures and higher differential pressures than ordinary Manganese Greensand. Tolerance to higher differential pressure can provide for longer run times between backwashes and a greater margin of safety.Systems may be designed using either vertical or horizontal pressure filters, as well as open gravity filters.GreensandPlus is a proven technology for iron, manganese, and hydrogen sulfide removal. There is no need for extensive preconditioning of filter media or lengthy startup periods.GreensandPlus is an exact replacement for Manganese Greensand. It can be used in Continuous Regeneraton or Intermittent Regeneraion applications and requires no changes in backwash rate, times orchemical feeds.GreensandPlus is NOT shipped in a regenerated form; therefore it is necessary, prior to use, to regenerate it by contacting the bed for a minimum of 4 hours.A regeneration level of 4 ounces of KMn04 or chlorine per cubic foot of GreensandPlus is recommended. Before placing into service, the filter must be rinsed of all remaining traces of potassium permanganate.GreensandPlus has the WQA Gold Seal Certification for compliance with NSF/ANSI Standard 61.PHYSICAL PROPERTIES CONDITIONS FOR OPERATION
