Subject: PMDD & Nitrate level
Good day all,
I was reading over the PMDD protocol by Sears & Conlin and I was unsure
about one aspect of the nitrate target reading. I could not find any
indication in the original post or follow-ups as to the type of test kit
used or how the results were reported. Is the target 5-10ppm Nitrate
reading Nitrate-nitrogen or Nitrate ion? I have two kits (Seatest FW &
LaMotte) that measure Nitrate-nitrogen and one (Seachem) that measures
Nitrate ion. I understand the difference between the two and how to
convert between them, but I need to know which it is. Pardon me if this
has already been covered.
Thanks,
Michael Stone
