Hanna Nitrate HR is in the house!

[ClownWrangler]

I find it odd that it took them this long. I mean, every person in the aquarium hobby tests for Nitrates while the other tests can be somewhat of a niche, particularly for those not keeping corals.

 

[Mattyreefs]

please will someone who owns this kit make a comparison post off your other nitrate kits plus this one as a comparison

the humdinger would obviously be this device, api nitrate, salifert nitrate, red sea. all on one tank water sample. nyos too but that's asking too much, if anyone owns all these nitrate kits you need help but I'd nearly pay to see the results

Don't have salifert or red sea but I'll do api, nyos and checker tomorrow and post results. After 3 days of testing, I've consistently gotten 18ppm on the Hannah. I was previously using the nyos exclusively and was reading it as 10-12 but now that I got 18 on the Hanna, I can see that I was probably misreading the colors.

That is a very good grouping. I was expecting fifty ppm differences among them

Looks like 20 across the board. Actually really impressed how close they all are.

Well wow! Kudos to api, my arch nemesis

I'd be curious to know how the Checker and other test kits compare with an ICP result from ATI. My assumption being an ICP test trumps them all

My last results, sans Hanna:
Salifert - near 10 PPM
API - between 5 - 10 PPM
ATI - 7.98 PPM
Conclusion: My kits are fine. Don't need the added expense of the Checker

 

[clhardy5]

My results:

Hanna: 14.5
Salifert: between 10 and 25 - maybe closer to 10???? (I don't like the spread of this test)
API: Between 10 and 20

I think I'll use the API for my frequent checking....and just use the Hanna to double check if there seems to be an 'issue'. Especially since the reagents are going to be a bit more expensive.

I'm looking forward to getting mine. The cost of the reagent isn't that big of a deal to me. I also do target shooting as a hobby. Each time you pull a trigger on a 9mm, 25 cents flies out of the barrel. I don't hesitate to empty the mag each time I fill it. For a tank like mine where I have to add nitrates and phosphates regularly or else they'd be 0, close enough doesn't cut it. I'm not about to go through the process of using the low range checker. The easier the test is to complete, the more likely I am to do it often. I'm excited to get mine after looking at these posts.

Got mine in the mail yesterday(thanks @MarineDepot!).

About to run a test between the Red Sea Pro and this. Will post results shortly.

Reagent costs don't bother me, it's part of owning the tank and the ease of use in which this test provides(one step, Vs. 3 with the red sea pro).

Mine is out for delivery. I've held off on my weekly water testing to try it out LOL

 

[homer1475]

Ok just ran both tests(red sea pro, and the Hanna), both came in reasonably close to each other for me to trust the Hanna.

Red Sea pro - just a little over 16, but not quite 32(range of the 2 colors in the high range kit)
Hanna - tested 3 times and all three times came in at 19.5.

Also just wanted to say, their cuvette supplier sucks. This is the second meter I've gotten that has had a cracked cuvette. Good thing they supply 2!

Can't wait to try mine out and compare to my Nyos. I have trouble judging between the 5 and 12 readings on there, and while ultimately not a huge deal, a reading of 10+ tells me to harvest my chaeto and a reading of under 10 says I can leave it. I target 5 for my tank.

 

[Devaji]

well i just ordered a salifert test the other day. guess i'll use that up and see how this goes for the next few months. hopefully there is supply issues with the regents and study reading over the next 4 months. then maybe i'll get one.
but to be honest i dont test a ton....I know I know

For anyone interested in pre-ordering additional reagents, Hanna charges $18 for shipping these little packets. Saltwater Aquarium is taking pre-orders with $0 shipping.

Just FYI......

 

[homer1475]

Just ordered 2 reagent packs from Saltwater Aquarium.

maybe if I'm really lucky....They will come early like the checker did?

BRS did say once that they were pestering Hanna for a nitrate test, Hanna said they were trying to put one together but just couldn't solve a few issues with it, I think BRS suggested a workaround for a couple of the issue with their testing...I think that is what Ryan was saying in one of his videos if I remember correctly.

One of the main issues with nitrate testing is interference by chloride, and hence differences based on salinity alone.

Normal kits get around that by just not being very precise. lol

I'm not sure if Hanna got completely around it or not.

 

[Randy Holmes-Farley]

See the salinity impact here (Table 2 and Chart 2):

Hanna low range nitrate accuracy, nitrite interference

Dan's being modest. He was filtering zinc out of the red sea NO3 test to improve color formation at least a couple of years before hanna's kit said we should. Sometimes I think he DIY's all his own tests, and just buys hobby kits to check his work. :p it's an impressive amount of color...
