Trident NP thoughts....

[simplety]

My np is out on most every phosphate test greater than 0.08ppm. Nitrate 2-4ppm. Would like tighter phosphate tests. Test results on phosphate are always either 0.04 or 0.05.

I got the NP last Friday. Since then the measurements have been horrible.

Trident NP
NO3 Bad NO3 Range
PO4 0.06

Hanna
N03 57.2
PO4 0.156

I have reset it, Prime, and Restarted nothing change.

It looks like this product was rush

New-ish Trident user here. I bought a 6-month batch of reagents and eventually noticed the calibration liquid. I didn't use it initially because I wasn't paying close attention...I used Hanna and SF tests for Alk, Ca, and Mag, and then I did my calibration. Things were looking good, but then I noticed the calibration bottle. Thinking I messed up, I did the calibration with the bottle, followed by a test afterward, and it was way off from the last Trident result, which was 3 hours previously.

I did another manual test and confirmed that the calibration bottle had messed up my test results. I re-calibrated with my manual tests, and all seemed well. Five days later, I did another manual test to compare to how my Trident was testing, and it was almost spot-on.

In short, I agree that the calibration liquid is trash. A local fragger who works from his house also said he never trusts them because when he got his first Trident, it was always off until he re-calibrated it to his manual tests.

Nitrates have been spot on with Hanna checker. P04 is a complete fail. reads 0 consistently while Hanna is 0.1
There is a bunch of complaints on the Neptune forum with nothing but crickets from Neptune

They pushed an update already that seems to have resolved the PO4 issues

I have the original and it works great. The NP so far is a piece of crap. The reading on my NO3 are in swings of over 20 and even the low is crazy high vs what my numbers really are. It says my PO4 is at 0 and stays there even after I calibrated it. I use two other manual test kits and even purchased the Hanna calibration solution and they all read very close vs the nonsense coming from the NP.

In almost 2 years of running the Trident I only calibrated it once and it made things worse. I “calibrated” it to my own kits that I trusted (for some odd reason.)

Come to find out, my Trident was correct and my magnesium test was wrong. Then add in Randy’s whole no magnesium testing and I never cared about magnesium again. I simply had the numbers because the Trident has them. I never paid attention. I actually didn’t even care much for the calcium testing but it was always accurate enough for me. I’d rather have Alkalinity, Nitrate, and Phosphate as my big 3. Dose calcium in proportion to my alkalinity and all will be well. 380, 440, 500ppm….doesn’t matter.

My Trident never had issue in almost 2 years. The drawer sucks. I agree there. The lines get kinked way too easily with that design. Neptune really ought to look at the Mini Trident design going forward.

There are thousands upon thousands of Tridents in use. The issues are relatively small with all things considered.

What is the mini Trident design?

Someone designed a 3d printed body to put the guts of the trident into that makes it into this.

I totally need one of these! My new Trident is gigantic! Thanks!

PM me. I have one I printed in all black. I can ship it to you for half the price if anyone else.

I returned my NP. It was hot garbage. Nitrates were accurate. Phosphate .04-.06 off in every single test.

I wish I could get a reading. They sent me a mother calibration solution and nothing. I even let them go so they read 0.11 on the Hannah and still nothing on the NP.

I just got my full refund INCLUDING the reagents.

 

[WhatCouldGoWrong71]

I am a trident user and love it. I verify every Sunday with with Hanna for alk and Salifert for Cal and MG. I do PO4 with Hanna and No3 with Salifert for a range, once a week. I picked up a Alkatronic and a Dosetronic at BRS for a really silly price. I've not used either yet, will be on my new tank in a month or two. I am a HUGE Apex fan. But, besides the big three, I really want to test on demand. And, I did the hack on my Trident so I only test Ca/Mg/ once a day. I am not even sure if I can integrate the Tronic stuff into Apex, I am new to this automation stuff. At the end of the day, I am trying to avoid subscriptions where possible.

I have 2 NP units, neither have readings even come close to Hanna phosphate or nitrate HR checkers…
In fact one unit has never read Nitrate: “ Bad NO3 Range”
…. Neptune support employees are top notch but I’ve yet to actually solve any Trident issue short of sending the Units back …

bump/following/ trolling for solutions

What is your NO3 reading? That error is saying your NO3 level is higher than the NP can measure (0 - 100 ppm). PO4 is 0 - 2.0 ppm. I'm pretty sure you would know if you had higher NO3 levels.

Did Neptune support ask for any logs after running your Hanna and NP tests at the same time?

 

[RusticsReef]

I said what I meant and meant what I said. I'm not the only one who feels this way. To be sure that I wasn't losing my mind I sent six bottles of calibration solution for testing. All six bottles were way off. Ever since I've been doing my own calibration my tridents have been accurate. When using the supplied calibration fluid they've been off. I don't need you to tell me what I need to say.

What's your manual calibration procedure for the NP?

can you explain how you "re-calibrated with my manual tests"?

Once you test with Hanna, etc., record your values. Then use your tank water as the "calibration solution".

You cannot do that with the NP. They currently do not support hobby numbers in the calibration task.
