Hey BM,

I'm not *quite* sure what this means. -->"around fivish 6.00" <-- but every test I've done on the FFOF has come out right at 6.5 out of the bag. Watered with the RO (@6) I'd expect to see runoff no higher than 6.3.

The MG runs near 7, so that may skew the results a bit? Maybe a little nute build-up in the MG? Have you flushed at all? There's no way the fresh FFOF alone would cause such a rise. (unless QC at FF is slipping)

BTW: I believe the 6.0 is correct for the RO, my distilled runs right there. My tap water..........ack. Right now 7.5! (and flavorful)
