Trident vs Alkatronic vs KH Director vs kh guardian

[leepink23]

For checking our test equipment we offer a reference fluid with a nominal value of 7.5° dKH.
You can check the KH Director results, if you like to 10 in a row. Most of these measurements will show the same value, maybe a few vary about 0.1.

Will the kh Director dose more during the day and less at night? I have really been interested In ghl especially with the upcoming ion Director, my only hold up has been pump head failure I have read about. But overall these look to be great products! I appreciate the input.

Just because you can't do it, that doesn't mean it can't be done. Trident's alkalinity assay has a precision (2 x RSD) of better than 0.5% of the measured value. We don't need to indulge in significant figure abuse in order to be able to honestly report alkalinity to two decimal places.

Sorry to hear you have so much difficulty with pump accuracy as an issue. Same for those probes you use. Trident entirely avoids that issue. Also sorry to hear if you have issues with QC on your reagent, or if you don't know how long your tubes are. I'm not sure what significant effect air pressure has on an alkalinity assay, or if you're just resorting to gratuitous FUD with that one.

I bet that if you COULD claim such precision, you would. Your rant reminds me of a story about a fox and some grapes.....

Trident has been my first choice except for my slow purchase fingers . So far a lot of great information has been shared, thanks for your invention and input. I do think all of these devices offer advantages.

I think the important thing here is actual user data of accuracy not lab accuracy.
I have ton of respect for vendors who try to stay humble and do not trick user in to thinking their equipment will have spec that you can only achieve in a lab.
So we have user report accuracy of khd of -+0.1, and khg. I am still not sure we have the data for the alktronik but it will come.
Soon we should start getting trident data. Not sanctioned lab data or beta tester data. Actual user data.
Well that is when trident comes back to market ofcourse. Where I stand, trident is still a theoretical device that have not been tested in the market yet.

I already have 2 khg their data. I might end up buying khd, alktronic and trident and do the test myself on a ref solution then publish some results.

Jim, your (mis)interpretation is very interesting, to say the least.
I am sure the reader here understands exactly my intension when I gave some examples for reasons of inaccuracy. If and which of these factors apply is a different story.
That you have another technology does not mean that there are no error sources. Anyone with a scientific background will agree.

As said, we have also a high internal resolution, we can easily print similar nice charts with as many digits as you like.

But let's see what the customer says - as soon as there are enough of your products shipped.

Sorry, I am not going to start a debate on that level, I'll leave this to others. All said what needs to be said.

Yes all let's not debate. The idea of this thread is collecting data reported by users. It is the only true judge here.

Yes I definitely want user data, I do appreciate the manufacturer input though. I am hoping someone who has owned multiple units will chime in as well. Also I stained our deck to save money to buy one of these devices
Edit: I could afford them without doing this, lol but saving the money does make me feel better.

Nice work!

I will say this,
Along side accuracy and performance of any equipment, the life of the equipment in the market manager too.
Being in the market for a year or 2 is also data to be considered.
Years of controlled environment testing is not equal to years of actual users testing.

I greatly appreciate some vendors staying on the high road. There's plenty of ways to support a product without taking shots at competitors.

I agree. I didn't like being called dishonest one little bit.

Agreed, clear contrasts between diffrent vendors. And there are trends and culture that you can almost immediately identify dealing with each vendor.
That's why I have learned to depend only on real customers data and experince. Not datasheet, not vendor promises not beta test testimonies...

 

[road_runner]

Exactly why I use a CaRx and not dose. Don’t worry much about it increasing my dKH through the roof. What is funny does everyone notice that a lot of the conversation in the thread really surrounds dKH? I wonder why?

Rhetorical questions guys

Because kh is what matter. Ca and mag will fall in check once kh is dialed.
Also coral have much more tolerance to ca and mag value range compared to kh.

Its funny, after ready thru this thread and see where this thread seems to be heading I see Neptune and GHL reps also on it, LOL!!!

After seeing how much static was created with the Trident release, and though I wasn't around the hobby yet, I am sure GHL had the same amount of criticism, and people are still crying over the alkatronic, I have learned that you have to make up your own mind on what you want to buy. You have to go thru all the reviews and pick out which ones you feel are honest and then purchase what works for you from that.

Well we will say again,
The idea of this thread is to share data by users. We should alwayes bring it back to this point otherwise this thread will be useless.
It's all about user data..period.

Well, there is this thing called pride.

But on a serious note a lot of it will depend on what ecosystem the hobbyist has in place. If one has GHL then that would be the wise choice to look for a solution. If one has Neptune then that would be the logical choice. If said vendor does not have a solution then it is again up to the hobbyist to see what the next step is with regards to looking at the product road map (if available) and if they can wait or pay for a complete change of their solution. There are pro's and cons of everything and having something already established is going to help guide.

The way I see it is a lot of angst and anger came out when I specific product was announced without a specific product launch date. Right away people thought of the worse case rather than taking a step back to see what it would mean for them to wait. If they couldn't and other products are on the market then it is a easier decision to pack up and resell what you have, if required, and buy the next kit. Neither vendor would have animosity if that was to happen. Sure, sorry to loose you but you have to do what you have to do. Peace be with you.

I pretty much agree with you - it is up to us, the hobbyist.

I disagree a bit. Buying something just because it's part of the existing system is what can lead to vendors release lower performance products and what lead to customers buying things to throw away.
That's why I value stand alone with controllers conpatibility...
But that's me

Then the title of the thread is wrong. It says trident vs. alkatronic vs. kh-director vs. kh-guardian. Title alone leads me to believe we are in a fight club and leads me to believe it is nothing to do with user data. Not trying to nit pick but nothing in it leads me to believe otherwise but I'm probably in the minority here.

Ha ha ha. Yeh maybe. I wonder if the owner of the thread can change the title. But change to what?
Comparing user data is basically X vs Y vs Z...no?!

If you have $5,000 invested already in a system and may only get a fraction of that money back are you going to switch? I think the foundation matters unless it is something disposable. It doesn't matter which brand you have, it matters be it an aquarium system or a home entertainment system. It matters when we are talking about the investment. At least that is what I was trying to call out. I very well could have failed or we can just disagree which is also fine. Just saying that is what I mean about ecosystem.

No idea - it isn't mine and I'm out in left field today - all good and I'll leave it at that I hope you are having a good weekend.
