Hanna Nitrate checker.....

SliceGolfer · Sep 28, 2020

I’m gonna pass on this, using my HI70427R reject button...

The last time I had to filter anything was for a strontium test and it was terrible... I really wanted this to be more simple then the video was, just to many steps going on. Red Sea for now then.... Also I do hate the packets but tolerate them to use the other checkers.

Wow was looking forward to this but not anymore lol. I'll just keep using the nyos kit it's way easier.

I just purchased a Tropic Marin NO2/NO3 test(s) and i think I could do those two tests faster than this one by Hanna? After all of those test steps I feel like a person should have results looking more like an ICP than just; "Hey, your nitrates are out of range high, Sorry!"

The 16-digit names for the parts makes this video fantastic. I mean, I can watch this over and over again, laughing harder each time, and there is no need to use weed.

I sorta feel a little bad for all of those poor souls that pre ordered it. I will never pre order anything. Ever. I'd be so upset about wasting that much money on something I would never use. I bet the replacement reagents will cost 20 bucks or more as well. This thing definitely wins snake oil of the year.

Definitely not user friendly. NAH.......

You guys are really funny. It’s not that many steps and certainly not hard to do. I think this will be awesome for the people who still need to know accurate low nitrate readings. And it also can be diluted down to 50 ppm nitrate.

Says the guy who will waste zero steps or money on ever using or buying one!

I will buy one as soon as the people using them say the results are consistent

Consistent compared to what?

Between the multiple dilution steps, and all the vessel transfers, almost nobody is going to be able to do this test with any precision. I'd be very surprised if its more accurate than the color scale tests for most people - just too easy to be inconsistent with - too easy to lose drops.

I mean - the last step in the video - is basically 'add 10 ml of the solution to the cuvette' and they've only got like 8ml of liquid left.

(Forget the first steps - where its add 1 ml of solution and then use the pippette to fill up to 10 ml line - instead of adding 9ml via a syringe. That's going to be a huge error source for people)

Wow. Watching that video was painful. I was quite excited for this one. What an epic fail from Hanna.

I recently starting using the NYOS kit and liking it better than the Salifert. I find it easier to read, coming from someone with partial colorblindness.

Thanks for posting that Chaswood.

Before today: I wish that Hannah would build a nitrate checker... WHY HAS THIS TAKEN SO LONG AND WHAT IS YOUR PROBLEM!!!!!!
Today: How could you create something so bad. YOU SUCK!!!!!

...although nobody has done better because it is a hard chemistry problem to solve for home use. I do admit that I don't know why somebody just cannot check the color of some Salifert results with an eye in a via in a egg.

I agree the measuring is a challenge. Using an accurate, graduated syringe or pipette is easier than eyeballing the meniscus on a vial for most people. Measuring technique is a challenge for labs too; definitely a skill and requires the right equipment.

I'd be less worried about loss due to vessel transfers, but the flat bottoms on those vials don't make it easy (lab containers have a conical bottom for that reason).

I totally agree. I do like the nyos no3 over the salifert but I’ve had difficulty finding it when I needed one. All of my lfs keep the salifert heavily in stock so thats what I end up going with. My target range is 10-25 so it’s pretty easy to read for me.

Viking_Reefing · Sep 30, 2020

That’s a no for me dog. Who really needs a super accurate (Provided that you don’t screw up a step) nitrate test anyways? Can’t say that telling if my nitrates are at 5 or 5,8 has ever been a limiting factor.
If this thing was much more user friendly than our standard test kits that would be a USP.

Bleigh · Sep 30, 2020

I think it’s complicated too. Plus, my nitrate has never been that low.
For everyone talking about the foil packets, these scuplas are a life saver. 2 for $5 on Amazon.

Last time I filtered something, it was in a tissue culture lab that required exacting standards and had no room for error... not the same conditions for my home aquarium by any means.

I feel like Hanna totally blew the market research on this thing - the problem with nitrate tests isn't accuracy - its that they're difficult-to-impossible to read for most people because most human beings are terrible at color discernment.

This isn't phosphate. I don't care about parts per billion. I just want to be able to tell where I am between those 5 ppm and 40 ppm blobs on the paper chart.
