Hello Tracy - The Chemsorb Sediment Backwash Filter would be a great solution for

The sediment backwash filter clarifies well water, removing very fine particles, rust and sediment without the use of chemicals or filter cartridges. Chemsorb is a high purity, low sodium, natural, zeolite mineral (14 x 40 mesh) that has an ANSI/NSF Standard 61 Listing. The material is mined, crushed, dried and double-screen sized to produce a high quality filter media that has a high through-put capacity at low differential pressure. Compared to filter sand and some other filter media you can get more water flow with less pressure lost.
Since you already have a cartridge filter, we suggest you keep that in line and install the sediment backwash filter prior to the cartridge filter, and change the cartridge to a 1 micron filter. The sediment backwash filter will keep the filter cartridge clean, and if there is any sediment less than 5 microns, it will remove those particles.
