Fleck 5800 programming details

[markches]

I ahve a Fleck 5800sxt with an injector OO, a BLFC of 0.125 gpm, and a 1 cubic foot resin tank. My water has a corrected hardness of 52 gpg. I am looking for advice on the C,BW, BD, RR and BF settings. Also whether it is worth setting it up as a double backwash in this instance. Thanks
