Anyone tried the Hanna checker with the new reagents yet?

[RSNJReef]

Hey everyone,

So I had bought one of the Hanna magnesium checkers about 3-4 months ago, and it was one of the original checkers from back in June. I had the high reading like everyone else, but just bought the new reagents with the powder, and while the reading are a little better, they still seem pretty high.

when I use the old reagent: +1600
When I use the new reagent: around 1500 (1540 on one test, 1480 on another)
When I check with my salifert test, I get around 1400.

Does anyone else still have this problem, and is Hanna changing just the reagent or the checker as well?

Got the replacement 2 months ago...haven't used it yet I was hoping it was good

Same here it’s reading too high for me 1570-1600, while my Red Sea test kit is reading 1450

They sent me a whole new kit. New reagents and new checker

i see a similar result too. Not sure if its good might completely return the whole thing. Tired of this back and forth thing

Results have been very close to my salifert. With Magnesium I've found stability to be the most important thing and it def helps me double check my trident once it starts to drift

I'll let you know. Waiting on one now!

I received a new box with checker+agents about two/three months ago and was advised to just toss the original one in the trash. Original readings were really really high. The new checker+agents work great as my levels are now as expected and I check weekly with the same results.

The original checker came with A+B liquid agents, the new checker comes with A (liquid) + B (powder).

Thanks for the follow up guys. I still have the original checker, but had bought the new reagents with the reagent b powder hoping it was just the reagents, but looks like the original checkers were malfunctional as well. I guess I’ll have to submit a replacement request for another kit.

Thanks all!!

I just received one of the new versions yesterday (7/2022 production stamp)

I purchased because my salifert was returning wonky results (2023 exp date but is probably a year old) - constant 1050-1100 readings, even after adding about 150g of Brightwells mag powder to my 220 (should have been about 50ppm increase based on their formula)

Hanna+new reagents first test came back at 1225 which seems much more in line for red sea blue bucket with no coral, bucket states 35ppt should be about 1280ppm mag i believe.

I was about to buy the salifert checker but now I'm thinking I should go with the new upgraded Hanna mg checker now.

All the Testers have a 8 pin plug near the batter connector. I'm guessing that each test is programmed for the type of reagents, so reagents + tester will be linked. They may also have versions of the testers which are not the same. It would be a shame if the test wasn't calibrated to the reagents properly - very unlikely they would fail to get it right. When comparing two testers, it's difficult to know which to rely on. Also have to remember that there is a margin for error in all hobby tests.
