Accuracy of Neptune Systems Trident NP

[Etto]

The post in question is about reagent preparation for installation or replacement when empty. It is not a daily task. One time upon installation or replacement.

Thanks

i shake the bottles 2 times per day and my readings are perfect on the trident they state to shake the reagents before hooking them up. seems to be working i guess

So, if I understand well, reducing as much as possible the sampling tube length will then reduce the bio film effect and improve the po4 measures. Not?

I keep reading these threads hoping to hear that everything is fixed and all is good again.
I'm waiting for the Maven to come out and hear how that goes for a couple months. Debating to myself if it's worth a major shift or not.

The sample line is a fixed length. Not to be cut or reduced in length. Any changes to it will throw off the results from the NP.

At the end those testers don't do magic, if the reagents are correct and the sample its not altered they have to work. Just as an automated Salifert test. I can not imagin Neptune Systems with all its big name selling a non tested product. But for sure its a new product and they have to send thousands of reagents sets with probably a new provider(as for sure they do not do their own reagent) and seeing the color differences from the reagents that people post it may be the issue. I am positive and I bet that they will solve it

My third NP got delivered today, not expecting much but we’ll see

And how is it working?

Hi, in case it is of any help to anyone. My trident NP has been running for 7 days and is measuring well, Nitrates are the same as my Hanna and Phosphate measures 0.01ppm less than my hanna PO4( ULR). So far I am satisfied with it, time will tell. I think I posted that I measured the phosphates wrong in some post, but it was me!, because I used the Hanna Hl736 ULR Phosphorus Checker which is the most accurate that Hanna has for PO4 but it needs the conversion (3.06x) that I have never done before. In fact thanks to the Trident NP I found the problem!

It’s a problem with the reagents. My first two (bad) reagent 3 batches were number
4GH1722

The good working reagent number 3 batch is 4GF1080

Wow Neptune customer service really is bad. I have complied with them, helping them out multiple times in making pictures of bad reagents etc. Put in hours of work. And their final reply is. The reagents color seem fine.
Paid 120 usd for 2 boxes of uslesss chemicals.
I’m really upset about this. If I knew this is how they would treat customers
Like this I would have never bought their stuff. Next to this my LLS also came broken straight out of the box.

The line as you are aware is a sample line - drawing water in from the source location to the test chamber. Are you suggesting that it is either contaminating the sample or that it isn't allowing proper water sample size and thus throwing off the tes

Has anyone else here gotten the new Trident NP and what kind of accuracy are you seeing from the device? Currently I have a few of these running and the readings are totally inconsistent, all over the place, and not at all near the actual readings I’m getting on other test kits. I’ve tried using the unit without calibrating and after calibrating and have issues both ways. Let me know if anyone else had this issue and how they may or may not have fixed it.

poor accuracy overall not happy. The promise of something easy and less effort got me spending thousands with apex but it has been far from it. Many issues. But in particular to trident np Hanna reads .08 but trident np always stay at .02 sometimes goes lower. But I know it's not accurate because an accurate tester or in a reef tank the values will change depending on feeding and husbandry and the trident doesn't reflect that. The Hanna does. Neither does Icp. Test. So you're telling me to keep spending 60 something on reagents that will give me inaccurate results what a money grab. Over apex Neptune in my experience has not made reefing easier just more complicated and expensive as the solution to most of my problems has been to get new things. Smh. Old school low tech seems more appealing. It has its place just not as something to be an advertised as making reef in easier. Don't believe just do a search on all the ppl that have issues with Neptune apex system equipment. Tons of stuff. So where is the easy part.
