How to Use the HI781 Marine Nitrate Low Range Checker

[jtreglown]

I'm pretty sure this is missing a step. It doesn't mention anything about adding the other 7ml of sample water before the 4ml of reagent 🤦🏼‍♂️🤦🏼‍♂️🤦🏼‍♂️

Props for your alk checker but man, this is crazy convoluted😆

I was having a relaxing morning at home just now and thought “hey, why don’t I check my tank’s nitrate level with my new Hanna Nitrate checker.” I then opened up the box, then opened
up the instruction booklet and thought “it will probably be less of a hassle to just scrub algae clean off of each rock in my tank than to do this test.”

It may be a few steps but for people like me that are color blind this is super helpful. I do wish it was easier but I can never tell the different shades on the card tests.

I am a fan of Hanna checkers and own 4. I like them for their convenience and ease of use. The testing process of this checker however is the opposite of that. I am stunned that you would produce a checker that is so misaligned with your brand position. I was extremely excited when I heard about this product and even more let down when I watched the videos on its use. I, and so many more Hanna users, expected better from you.

Thanks for the video so I can avoid uv saved me money on ordering one way too many steeps not seen one good review

Hi Hanna. This test is more complicated than previous ones but for me the extra complication is worth it for the confidence level I get from the output. After many years I am now confident in my Nitrate levels.However as mentioned in other posts below it is inexcusable that the video instructions are wrong! It's now end Dec 2020 and the video was first posted end Sep 2020 and many other have commented to the fact that the in the video there is no mention of adding the sample to test! In your video you suggest you start with 5ml of Reagent A and draw off 10ml of test sample which is obviously impossible. Please fix this video ASP so that others can correctly use and get the benefit of your test kit.

That’s one of the reasons I don’t use my calcium checker and now you have this more complicated? Nonway

[kevinchiara]

the Red Sea test takes like 10 minutes and has three steps and it is so hard to read the result because the shade of pink. I don't think this is that complicated. Amazing for people that are colorblind as well!

Thank god i saw this. Definitely wont be buying this hunk of crap. They legit have a filter 🤣🤣🤣

[garrycole]

People are so overreacting, yes it takes 8 minutes for the actual clock to run down. In the mean time do an alkalinity test or a calcium test. I do this all the time. I don't just check one test at a time, sitting around. Right now I am doing the nyos nitrate test and during the 5 minutes wait, I do my hanna phosphate test. Organize and you can do all your test quickly.

[salvatorepalazzolo]

This is a 20 minute test lmao. They should’ve just aligned with Nyos and used a check to read their clarity

I was wanting a nitrate Hanna checker so badly. Now I don't want it anymore.
More expensive should be for less hassle, not the opposite.

I think this is very well done to give us a digital nitrate measurement. In Short (Take water sample, Put Liquid Reagent A in, Put Powder Reagent B in. Filter with syringe, put in meter, remove 8 minutes later and add another powder. Done) To measure 5-50 here's the dilution. In Short (Put sample in, add freshly mixed saltwater, Put 7 ml of mix in vial and do the normal test) BOOM!

I am only hear because when I opened my box and saw all that stuff the only words I could think of was good grief. This is intimidating.

[huntersmall]

Who sells the reagents cant find them anywhere

[indrabg]

When you add the sample, how much ? The video only mention adding 4ml reagent A

[toddeddie]

Is it 4ml or 5ml of reagent A. Not the quantity level the dropper, what is the actual volume of reagent A I need? I get either 0.0 or >5 depending if I use 4ml of A or 5ml of A.

[ricardovarelatello]

The filter disc, how many times, could be used ? How many test is posdible to do with the test package ?

[acuariomarino]

How many ml of water from your aquarium did I use?
