New Hanna Checkers - Hot or Not?

[@jeremybarr1726]

Looks like this isn't ready for primetime or they are not calibrated correctly. Thanks for doing this video as I was going to pull the trigger on this, cheers!

[@ParkersReef]

Glad it helped

[@markmckinnell2204]

Sam - the U.K. Hanna rep told me they are replacing the magnesium reagents for a powder sachet for an August delivery and they will be simpler to use and they will replace any reagents you have already bought - not bad customer service.

[@ParkersReef]

I heard the will replace the reagent but it won’t be a powder but a correct strength liquid. A good response indeed, although a little late considering the number of complaints they had about the unit on day 1

[@markmckinnell2204]

@@ParkersReef Like I said Sam - Hanna U.K. phoned me as I sometimes buy things directly from then and had asked the question about replacing the duff reagents and that’s when they said it was changing to a powder and it would make it less hassle as it would work like the phosphorus and high range nitrate checkers do - I will see when the new stuff arrives next month 🤔

[@ParkersReef]

Interesting that they are giving different answers to different people.... I guess we'll find out soon!

What made you think you wouldn’t get any ammonia from your display tank

[@ParkersReef]

Cycled display, shouldn’t see any measurable ammonia unless something is dying

Heyy Hanna came up with a fix to the issue of the Magnesium checker reading high. Apparently you fill out a form on Hanna's site and they'll send a new reagent.

[@ParkersReef]

Yeah…. After telling everyone they used the checker wrong 😅

[@starfighter1977]

Interesting video thanks Sam. Can you do something about the over head angle? It was making me feel queezy. It’s like it needs to come back towards you a bit!

[@ParkersReef]

Yeah changed it for the magnesium test 😅

[@leighwhite1898]

I broke my hanna taking off the base plate, always feels wrong to me, surely they can come up with a better way

[@ParkersReef]

its terrible isn't it!!!?

[@ChrisStevensWA]

I have a NYOS Mg and started with Hanna Mg last week. The Hanna results were only slightly higher.

[@ParkersReef]

Interesting. Anything different you did?

[@ChrisStevensWA]

@@ParkersReef BTW - slightly higher was 1350 to 1425. I now suspect NYOS has been reading high (or I am not counting drops correctly/bad colour perception - why I wanted to try the Hanna!) and I tested both kits in NSW and both were higher that I expected. On my last ICP NYOS read 1400 and ICP 1315. For now, taking 150 (very scientific!) of the Hanna reading gives me a realistic result.

[@markherrmann5592]

It would be great to get Hannah on or seek comment to confirm the error or check the procedure. If it is a batch issue, they should recall and fix it. Not great for their company credibility overall.

[@ParkersReef]

Hanna currently seem to be giving random feedback from user error, to typo on instructions... I'd say they're scrambling :)

[@XMRNYC]

There seems to be a consensus on r2r that they test high. Perhaps I should return mine before opening.

[@ParkersReef]

I personally would...

[@jakdstudios980]

interesting the first time i used it mine was way to high i found the add on tips are to loose and let in air , i took a great deal of trouble to make one of the tips fit properly last 4 test are have been realy good Hanna need to sort out the tips so they fit correctly

[@ParkersReef]

Yeah it shouldn’t be this bad for so many people :(

[@matthewking6509]

Hey mate update on the Hanna , took it back to uni hill they sent it back to Hanna it’s getting new regents sent out so probably a chemical concernteation issue hopefully this fixes it I love having all my testers being Hanna .

[@ParkersReef]

Yep they announced (in America at least), that they stuffed up and new reagents are coming. Pretty embarrassing after telling early buyers that it was user error 😳😳😳

[@matthewking6509]

@@ParkersReef that’s so Embarrassing just goes to show sticking with “the customer Is always right “ is the best outcome . When i contacted there help team I was told the temp of regent must be to hot or cold . Then they just said take it back to your retailer .

The Aqua forest reference solution is for use in 2mls of tank water not 10mls?

[@ParkersReef]

Not sure what you mean sorry?

[@samthemanoffishing]

Brought my Hanna mag checker on release, sent it straight back to Hanna as I thought it was faulty with inconsistent readings! They said no fault with the checker, so took it back the shop where I had it from, and they sent it back to hanna, it came back as no fault but they sent me a new pack of reagents. Getting rid of mine doesn’t even give you a rough idea where my mag should be compared to icps absolute waste of money

[@ParkersReef]

yep -defeats the purpose if you can't trust the results!

[@danfightforthetruth]

Update :: 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

[@ParkersReef]

be good if they put out a post or some official comms around this. I appreciate the update, but this isn't the first place I should hear it!

[@Sammy31Dee]

The best manual test kits are as follows.... Hanna for Alk Red sea for Cal and Mag Nyos for Nitrate and po4 Salifert for Potassium I've tested many against icp and my trident....these I absolutely trust

[@ParkersReef]

Good to know, thanks for sharing :)

[@Sammy31Dee]

They're also imo the easiest ....if you try em you'd probably be like Dannnnng he won't lying 😏

[@tranquilwaters917]

The Mag checker in not ready for the general public. I have had people tell me they had multiple people testing the same tank and getting results all HIGH, same tank same people with the Salifert same tank, were getting close to identical readings to the ICP test.

[@ParkersReef]

Yeah definitely seems that way

[@matthewking6509]

Hey mate , good news Hanna new reagents came in 3 weeks back I have used it over the past 3 weeks and it’s pretty much perfect so another Hanna tester for the collection they changed the part b liquid to a powder so it’s even easier too .

[@ParkersReef]

Yeah picked one up myself

[@paulmeneely]

Ho no! I have age the Mag Checker for a few weeks. Have not got around to using it yet. I’m hoping if there is an issue Hanna will find a solution .

[@ParkersReef]

Fingers crossed!

[@matthewking6509]

Got mine a week ago at uni hill aquarium it will be going back this weekend . Did 3 tests on it flashed above 1800 . My aquaforest mag test kit shows 1400 I love Hanna for my dkh, phosphate and nitrate but the mag has been a flop glad it wasn’t just me feeling I did it wrong .

[@ParkersReef]

Yeah it’s back to the drawing board on this one I think…

[@fuffoon]

I like the phosphate test. But I can't see changing from JBL count the drops for Kh to something more complex. Simplicity wherever possible. I have cubic meters of unused tech taking up place in my workshop awaiting a reasonable offer or a needy reefer.

[@ParkersReef]

Yeah as a gadget freak I get drawn into this stuff but sad to say this one is a bit of a bummer

[@davidhughes1843]

I bought the magnesium checker a couple of days ago and my three tanks came back with 1800 as a result so now it is back in the shop where I bought it and I am waiting for the shop to sort things out for me but this video has made me nervous. Good video as always

[@ParkersReef]

glad I could confirm your thoughts on the unit. I don't thin hanna should have released this, clearly something not right...

Very refreshing to know I'm not the only one that dislikes the base plate. Shame the Mag tester wasn't showing usable results. Glad I held off.

[@revZ098]

@@ParkersReef strangely enough I got someone to test it and compare it to thier Icp test results and it was pretty much bang on with the Icp results he got. And I asked him what he did different and he said he used his own syringes and not the ones provided by Hanna in the test kit. I haven’t tried it out myself with a different syringe but it could be worth trying. Especially since I noticed that the Hanna syringe tips doesn’t actually seal properly when putting them on and just kind of falls off with little force.

Interesting…

I recently uploaded a magnesium meter video. And I compared it to red sea magnesium. The two values were found to be about the same. I think Hannah's meter is accurate.

Is it possible that not using the nozzle of the syringe affects the actual volume of the reagent that is being added? I've always wondered that with dkh Hanna checker, because I never use the nozzle.

[@ParkersReef]

nope, volume remains the same.

[@PazLeBon]

@@ParkersReef only if the nozzle is empty i guess

[@michaelhoward7115]

Sam, wonder if you experiment with the amount of the purple reagent for the magnesium checker against the reference solution if you can come up with an accurate reading. Maybe there is too much of the purple reagent, even though that is the instruction?

Yeah could be worth playing with, but I suspect that should be done at Hanna Headquarters, not on my time and reagent on my dime ;)

Hey Sam, your test has confirmed that the reviews about the Mag checker reading high. Mine will be here in a couple days and I’m curious how it compares with my trident 🔱 I currently have the aqua forest test kit but think I will try the salifert against the mag checker as well. I’ll be using the ammonia checker for my fish QT as it appears to be pretty accurate. The current line of Hanna checkers are usually pretty spot on and I Hope they (Hanna) take these reviews seriously.

Interesting - I’ve had mine since it was released. Kept getting 1650, just retested with 5ml instead of the advertised 4ml. Came out at 1430 - my last icp was 1415 so much more in line with 5ml. Would be good for Hanna to confirm

[@ParkersReef]

yep - Hanna need to confirm officially for me to waste any more reagent (or time) on this :)

What is the model number of your magnesium checker? I bought one from Aquaristic HI719 and it is completely different to the one your are demonstrating.

[@ParkersReef]

How so? What is different? I’ll go check the model number now :)

[@ParkersReef]

HI783 is my model number. HI719 is the freshwater magnesium I believe?

[@starfighter1977]

Hi Sam, one thing occurred to me, where you didn’t use the tips for the syringes, doesn’t that meant you didn’t have the right amount reagents? I.e you are missing a tip full? Would the instructions not have allowed for that? My salifert alk test actually states about it.

[@ParkersReef]

Having the tip or not does not affect the volume collected by the syringe. That is why you measure to the base of the plunger, not the fluid.

[@DanMirkz]

Yeaaah I'm gonna go with a big fat NOT. For me personally, 15 mins for a test is an annoying amount of time to wait not to mention the amount of steps it takes for the Ammonia test. The Mag test appears to be a mess if it's reading so high compared to your several other methods. Think I'll keep with Salifert for those ones. Cheers for the vid!

[@ParkersReef]

yeah some hanna are awesome, others are far from it :P

[@dereks3207]

you may want to try your own battery on that mag test. my PO4 kit goes nuts with results if the battery is low. i never trust a battery that comes with any electronic device.

[@ParkersReef]

yes is a good point and I should have (although the checker is gone now). Not that you should have to, but would be worth a try

[@burder123]

It will be the same as the calcuim tester there is a +/- of 20% as I tested My water 3 times and got different results ranging from 444 up to 497 and its with in the accuracy of the test

[@ParkersReef]

Yeah not much point with that range…

[@starfighter1977]

Hi Sam, when you look at it, you got results that you were surprised by and actually thought might be wrong. Maybe it’s because you didn’t follow the instructions? Have you tried it with tips on the syringes and doing exactly, word for word what the instructions say. Sorry, it’s just the scientist in saying if you don’t get the results you were expecting, look at the method, and you did deviate from the manufacturers instructions.

[@ParkersReef]

I actually did try with the tips on the syringes, but they kept falling off. But I’d love to hear how you find the unit, didn’t work out for me :)

[@HarryESwan]

A bit off topic... Who built your aquarium?... For some reason i thought it was Water Box Aquariums but I called them and they would only sell me a full system, not just an aquarium. Perhaps I'm wrong?..... Awesome videos btw.

[@ParkersReef]

Yes waterbox custom made my tank. You can watch it all here: kzbin.info/www/bejne/gKbaYmaAa8aAi9U But I believe they do not make custom aquariums in all regions
