Hanna Nitrate HR Checker

[highest_tides]

Up to 75 ppm using one reagent

Too bad I just ordered the low range checker. Like literally yesterday lol

I saw the checker at RAP. Pretty cool, but will not available till June

My HR checker keeps reading flashing 75 which means out of range. Checked on API looks like zero to 20. Something is off. Does it mean my nitrates are too low for the HR Checker? Confused

I have the lr checker .
too many steps and a huge pain in the butt .

Got both after using the low range. That's crazy. I don't know what's right anymore

Knowing what your reading prior to testing defeats the purpose of testing IMO
Above and below 5ppm makes a difference if a dilution step is needed
Having a fresh batch of saltwater made up for the dilution step is a pain .

Find the one kit that works and stay with it .
Sometimes new doesn’t always mean better.

Love the new high range checker. So quick and easy. New staple to go with my dkh and po4 checkers

I got mine about a week ago, totally replaced everything else for checking nitrates. I love it! So simple with only one reagent too. Too bad the reagents are out of stock.

I like the ease of it but it keeps showing 0 nitrates in my tank. Maybe it’s true but I’ve upped feeding so we’ll see what it says in a few days.

I hope it’s not defective.

Had such a hard time telling 5,10,20. First use spits out 8.4. So easy and solid result.

Which tester are you using ?

I despise the lr nitrate but if the hr works great and can measure low I will grab it

I figured out what I was doing wrong. I was shaking it for the full 2 minutes instead of seeing the color change to pink then stop shaking. My nitrates are crazy I'm so embarrassed. Now I know why my sps are brown. My API test was soooo wrong. Love this thing!

They have some on the hanna website

I bought it 2 days ago from a LFS, and I got 0 Nitrate..........is that even possible?

That’s not what the instructions say, you’re supposed to shake for 2 minutes. Why would you think this is the way to do it ?

Same here and I am very sceptical.

Well I was watching a video on YouTube and he said shake it for 2 minutes, but he only shoke it until it turned pink. I was shaking it for 2 minutes and it turned orange before I put it in the checker. Mind you before I was getting the 75 flashing for 4 tests while the api was giving me a reading of 20 at the most. (Only ten tests in the kit, getting expensive) So I thought dose some nopox, wait, shake it until it turns pink, about 1 1/2 minutes then put it in. I'm embarrassed to say I got 69.8 doing it like that. I also didn't put the glass inside the aquarium and used the pipipet(excuse spelling) to gather my water sample. Either way my nitrates are through the roof. API was really wrong or my test kit is old. Going to dose nopox again tomorrow. I already did a waterchange yesterday.

Shake for 2 minutes then place in the unit and hold the button to start the countdown. Same as the po4 checker
