What do you think salifert's % is....its not about the # it's about the trend
+1. For me it is annoying that someone comparing colors to a chart thinks it is more accurate than a digital reading. I ran my 1st test today with hannas new mg. unit and it was right on. Note: In th the instructions it says to be percise in how you do xyz and spells it out otherwise your your results will NOT be accurate. just say to those who like to hear the,selves complain. Especially newbies, IMO just my 2 cents PS: I like ELOS red sea and salifert test kits.What do you think salifert's % is....its not about the # it's about the trend
The o.p
premium aquatics and I think BRS has them now.
Awesome thank you I just filled out the form!!Hello from Hanna Instruments,
I am on the aquarium team, here to address the Magnesium Checker issue.
I am posting this same message on various threads regarding the Magnesium Checker so that as many people as possible get the information.
First, here is an FAQ with answers:
1) What happened?
As many of you know, Hanna Instruments prides itself in accuracy. We do extensive R&D before releasing products – what happened with the Magnesium Checker was a unique combination of unexpected factors. Our manufacturing facility is in Romania, and shipments from Eastern Europe were delayed in the Spring due to events in that area. With this, the initial batch of Magnesium products were in cargo storage for longer than anticipated. While the cargo containers sat for extended periods in the Spring, the temperature in the containers increased. This resulted in longer than usual exposure to higher than usual temperatures, which in turn caused one of the reagents to expire early. The products passed R&D inspection on site, and we’ve never had them degrade in transit before, which is why we were surprised about the issue at first. And why we are grateful that users like yourselves reported it!
2) What did Hanna do to fix the products?
The issue was one reagent expiring early during extended high-temperature exposure in the cargo containers. To fix this, we were able to greatly improve the temperature stability of this reagent by reformulating it from a liquid to a powder. This means that Reagent B is now a powder for this product. Our other Checkers have a timer built in for the dissolution of the powder reagent, so we added that to the new Magnesium Checkers too. That is the only difference in devices, but because of that, we are sending everyone who purchased the initial version a new Checker with the timer built in!
3) Why has it taken so long?
Resolving this issue took several steps. First we had to reformulate Reagent B into a powder. Then we had to add the timer into the production process for the Checkers. Once those updates were made, we had to repackage all the previously produced items with the updated ones. And of course, we had to figure out the logistics of replacing these items both for customers such as yourselves, and bulk purchasers like LFSs and major websites. We also found new transport options to avoid extended international shipping delays in the future.
4) How is Hanna going to make this right for the people who already purchased?
We will send everyone who fills out this form: HI783 Marine Checker Reagent Issue Form free replacements for whatever Magnesium items (Checker and/or Extra Reagent Packages) were purchased. Please fill out all fields!
5) How do I know if I am in queue for the replacements after submitting the above form?
I receive all the form submissions. My apologies that there is not a confirmation, but once you hit submit I do receive it. We are on track to have all current form submissions fulfilled by the end of October, and new submissions as soon as possible thereafter.
Please see our official customer letter below for more details:
These Magnesium items will be available again from your LFS and online sources soon.
Thank you for your patience as we have resolved this issue!
All the Best,
Hanna Instruments
