I think it's the other way around. To maintain 5-10 ppm nitrate, with
the
Lamotte kit you want to be in the light pink range of 1-2 ppm
nitrate-nitrogen.
You multiply the Lamotte reading by 4.4 (if memory serves) to get the
nitrate level.
Don't panic if your Lamotte reading is 5 ppm (nitrate-nitrogen). A 20
ppm nitrate
level is normally not a disaster if other parameters are okay.
Good luck, Steve Dixon
