Neptune Trident NP and new DOS!

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)

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.

My Hanna is busted - I did Hanna & Salifert tests AND took a sample to Aquatic Collection to use their AquaSpin. The Salifert was close to Aquaspin (roughly 0.03-ish) and my Hanna was reading something insane like 0.3

Trying to avoid buying another $70 Hanna checker if the NP can get working "properly"

I have the Hanna-not sure I trust that either based on discrepancies with my ICP tests that says Hanna is .1 above the ICP on average. But at least I have some consistency.

Yes I don't know enough about any of them to speak to accuracy. Only pointing out with salifert p04 accuracy in terms of a precise range is almost impossible. Even for the point of determining if you are rising over time or declining. Mine always showed same results so really no help. I imagine by the time it showed a visble color difference you would already have major problems. Just my experience with that specific test. All the other saliferts I had no problem with getting a clear determination.

ya for my purpose I just have to have a non Trident tell me whether on not p04 is zero. I even dosed liquid phosphate and Trident is still reading 0

I’d just throw out there that you’ll want a test you trust on hand to check the Trident NP results against occasionally even once you have it working well. So probably should have a working Hanna ULP regardless.

By analogy I’d never recommend someone rely entirely on the regular Trident readings without being able to manually test for Alk, Ca, Mg as needed.

ya I totally agree. ill get another one eventually. The 774 hasn't been available w/ Prime on amazon - buying from the online reef retailers takes longer than waiting for a weekend trip to AC
 
More fun. Today's NP's nitrate reading jumped about 20ppm from yesterday. Salifert says between 10 & 25 :D
