I don’t trust salifert for p04, all the other ones they make are straight foward. Po4 though impossible to tell range with any confidence. Maybe consider a hanna for po4 or different test.Nope lol working with Neptune support now; submitted a bunch of debug logs etc yesterday and waiting for their engineers to diagnose what might be happening.
Since the last update:
- I've done 3 or 4 water changes to bring nitrates down. Salifert is reading about 20 now where the Trident is reading 50-70 (depends on the day).
- many hours after a 50% WC nitrates went from 60 to about 78 (Salifert said they went down)
- Due to frustration on my part I did a "reset" on the NP and since then Po4 has been reading 0 (Salifert disagrees and says im between 0.03 and .1 somewhere - cant tell from color)
