Trident Support Curiosity

[User1]

heres what I would do in my opinion. get a couple different calcium tests. average those and set your trident calibration to that number. then during that same time frame take an icp test and send it off. if the number comes back close enough then keep it there.

This is what many are doing. They let the Trident run its course and calibrate it after a couple days if not a week at least based on what I've been reading on other forums. In the process they compare the results on a day they set off an ICP test (which also has many questions believe it or not based on its own calibration and what they do between tests) and manual tests.

Overall it seems like most have been pretty consistent and accurate. Each unit is tested before it ships out of Neptune so it has to be within a set limit before that one would think.

Trying to test different tests against each other is a way to go mad. They are not the same, they don't test the same, they have different +/-. IMO, you have to pick one test and go with that because they aren't really going to match up. I wouldn't make the trident agree with another test kit, because I have no idea if the other test kit is right.

Well said.

I just got off the phone with Neptune and he said the Trident is for precision first accuracy second.

That’s not what they said though

Or maybe he has better reading comprehension?

From the OP: "My gut does not like this answer and I am about to order an ICP test to try and verify closer. I just got off the phone with Neptune and he said the Trident is for precision first accuracy second."

Huh?

OP stated he was on the phone with them(Neptune).

Then another member stated that’s not what they said.

I stated it must have been a 3-way, for someone else to know what they told him.


Am I missing something???

You are, yes.

 

[DaneGer21]

You are, yes.

Interesting, I’ve read no different.

Again, OP was told by Neptune.

Next member said No they didn’t.


What am I missing??? And how does another member know what Neptune told him on the phone???

Below is the exchange. I believe Ca1ore was saying that neptune didn’t say that it was precise and not accurate, but rather that they prioritized precision over accuracy. But the two aren’t mutually exclusive. Just because precision was prioritized doesn’t mean that it can’t also be accurate.

I am just blown away I suppose by their answer of how its precise not accurate. That’s why I bought it!!!!

That’s not what they said though. Something can be accurate and precise. Makes sense to prioritize consistency over absolute accuracy. Try testing the calibration solutions in your test kits and see what reading you get.

Read the bold text above but you do you. OP said what they told him...

Exactly how does he know that’s not what they said?

Exactly, Neptune told him one thing, another member said No.


I’m confused NOT as to what was stated, but as another member says NO.

Soooooo, I said it must have been a 3-way call for him to know that Neptune never said that!

 

[DaneGer21]

That’s like me saying I stopped at McDonald’s this morning for breakfast, and someone else saying No you didn’t. Again, were they at breakfast with me, No.

In the first post he said:

Then later he said:

I think that was him misinterpreting what they said on the phone. It’s unlikely that neptune said that it’s not accurate.

I suppose it would have been more accurate if ca1ore said “That’s not what you said they told you” rather than “that’s not what they said”

Unfortunately you aren’t stating anything new that I haven’t read.

How does the other member know that’s not what was said. Have phone transcripts been printed? Haha

This is off topic now. What I stated as a joke some of you have taken to far.

Sorry, I hit reply before I finished typing. I edited my post above. But perhaps it has gone too far. In the end it doesn’t really matter anyway. It is what it is.

So I just used my new Hannah reagents that expire 5/21 instead of 7/20. Premixed Reef Crystals (three weeks old) shows 526 with new reagent. Tank water shows 504. Based on the Trident saying 437 for my premixed water and 326 for tank water....I am going to have to go with Trident for the win. That is not within Hannah range of error at all...

I guess my tank is proof you can run calc in the 320’s!!

Yeah, my trident shows that my alkalinity and calcium were both a bit lower than I thought (although not down to 320). But like I said above, I really think that stability is key over specific numbers. The animals will adapt to a pretty wide range.

The tank looks great though

LOL Ha! You'd have to pull an ICP test out to verify really. Although Neptune have tried to suggest ICP is suspect compared to the Trident previously also...

Both Email and phone exchange occurred. The three way call was a type of “thats what she said” joke I believe.

When I asked if I were to do an ICP test and calc was indeed in the 320’s, the rep said via phone that I would then just have to calibrate the Trident to that then. He did not have any explanation why the Trident COULD be off that much just that it is more precise than accurate. From my view, it should be both even though it is not. If we were talking 20ppm I wouldn’t be having this conversation. 100ppm is a much bigger difference.

Anyhow, this whole thread is now like a cow’s point of view.....”It’s moo.” I think I have proven via testing how far off Hannah is between NSW and OSW.

That's an interesting post. I just installed my Trident last Saturday. I feel I still need to wait a little bit before I can chime in, but so far, my levels (I did not calibrate the Trident yet) seem to be right in comparison to my Hanna, Salifert and RedSea test kits, IF i consider a proper deviation. Maybe you had a bad batch of reagents? Or perhaps, you had you calibration solution bottle opened for too long (over an hour)? Just some quick thoughts from what I've heard...

Totally agree I also installed my Trident Saturday I am told you have to wait before calibration. Other than that my numbers align perfectly with the Trident

Terence on the forum said 48-72. I waited until 80 hours. Maybe longer helps but I followed the manufactures recommendation.

 

[smartwater101]

100 off is unacceptable. Not sure why people keep trying to convince you otherwise.

If you have to offset the trident to match multiple tests kits and ICP, then go for it. Nothing wrong with giving it a proper baseline.
