HANNA Marine MAGNESIUM Checker - Mr Saltwater Tank -Raw, Uncut & First Impressions

In this episode of our series, Mr. Saltwater Tank - Raw, Uncut, and First Impressions (RUF), Mark will look at the Marine Magnesium Checker from Hanna Instruments. Join us as we run a blind test on Mark's tank with this checker - we'll show you how easy it is to use, what we like about it, and discuss how often we'd use it to test magnesium in our tank.

Why would you like it, if it gives out high inaccurate readings 😒 look at the forums and see for yourself.

[leewishnov]

Already seen others saying they may have misprinted the amount of reagent which is why everyone is reading high on it for everyone.

[xxKILLBOTxx]

I pre-ordered the tester. Mine tested high as seen in the video. I reached out to SaltwaterAquarium and tried the suggested 5mL of Reagent. This tested low…. I was debating on returning unit… I decided to test today one last time after reading every word of the instructions and much effort to be EXTREMELY PRECISE.

SOOOO UPDATE TIME….
Today I did my Mag tests using the stated 4mL of Reagent A.

I disassembled the silicone from the tips, cleaned each tip thoroughly, made sure when I reassembled the silicone was completely seated in the tip…

Then I made sure to draw the EXACT correct amounts of liquid into each plunger, wipe the outside of each tip, and make sure that not a drop escaped or was left behind…

I tested (2) reef tanks this way and BOTH TESTED ACCURATELY!!! TODAY was the first time the new checker has made me happy!

I am thinking I may order a 1-10mL adjustable micro pippette on Amazon to ensure consistent accuracy…

P.S. A refill for my Mag tester would be nice since I functioned as Quality Control for Hanna. 😜

I own this tester as well as the Aquaforest test kit. I also took a sample from the tank on the same time and sent it off to ATI. All three including the Hanna were within 75 points of each other.

I'm using both Mr. Red and Hannah. The two values are the same when comparing and measuring the latest product with the red seed. I'm quite pleased

[Emmanuel-rseu]

They should be recalled..inacurate results.

[lovermansmith]

Good job ! I like cost per test comparison too

[mwilk]

It will be interesting to see what your results are. I’ve tried it with the syringes and tips provided and I’ve tried it with an E4 adjustable pipette. No matter what I get readings that are 300- 400 ppm higher that what Salifert reads. This seams to be the case with a lot of people who own this checker.

Hanna USA/EU is solving wrong measurements of Mg level due to bad quality of reagents (raw material)   - sale is on hold / expected new reagents within 07-08/22

Great video
I did several test with new magnesium Hanna checker, the results was 1750 to 1800 ppm
According to other people test, reef to reef, YouTube, and other sources it’s all has 200 to 400 ppm over the Neptune test or nayos or Red Sea …
The results is to high by far

[strats]

I have used the Hanna Marine Mag tester three times now. I also use the Salifert Mag test kit. The Salifert is giving readings in the 1200 range. The Hanna is giving readings in the 1500 range. Thoughts??

[SammyDee]

Did you get a proper reading ....every other reviews says it reads 3-400ppm high

[dankfir]

I already own 2 units like this.
both gave me wrong and too high results.

Something wrong in this checker, you can compare it to ICP .

this item looks defective from head to toe.

So, Why are you so happy?
just that you will not need to read the color any more?


LOL....

[strats]

Love the music at the end of the video.
I have a Trident, but I also test weekly. There are +/- for errors on both trident and hanna testers.
What are your thoughts on calibrating the trident to the readings from a hanna tester vs the calibration fluid that comes with the reagents?

[khanhpham]

what to do with magnesium test result 1800?

[Reefkpr]

You said ZERO about it reading 1755!!!! What's your Trident Seeing all over the internet that these testers are reading High! We need answers from Hanna. Seems like SaltwaterAquarium can make that happen?

[paulukreefer]

Third review I have seen on this and all
Of them are reading high… I have all the other checkers but this one is a worry

[bluereef]

Sounds like these readings are high. Let’s compare it to ICP test. Rather use Salifert which gets 50 test that last for long time. .

[erikanderson]

Pretty disappointed that I preordered one for myself and one as a gift. They are so off that Ive decided not to give the gift one to my friend.

[jayrod]

What good is ease of use if it is wildly inaccurate? I assume you don't run your reef at 1755. Giving this a positive review is shameful. What a shill...
