hanna checker

Which hanna nitrate checker should I get and why? High or Low range?

Fish Think Pink · Oct 2, 2021

I *hate* my Hanna Nitrate LR checker - read the instructions online and you'll understand why - everything short of stand on head - but if that made some of those other steps go away, I'd try a hand/headstand.

I *love* my Hanna ULR Phosphate checker - easy 1 packet 2 vial but I think this chart is missing from box:

Hanna Alkalinity and Calcium testers are pretty straightforward.

Don't have 1st hand experience with other Hanna testers

100% high range.

High. I've never used it but the low range checker has a horrible reputation as being difficult to perform. I was going to get it when it came out, but I watched a video of someone performing a test and changed my mind.

Concur with the above. No complaints with the high since it's really just one step of adding the reagent power.

My lr will not c2 after 3 months, got the hr today and tossing the lr, yayy.
Hr so much easier

I’m also looking at getting a couple of Hanna checkers. The Nitrate is a no brainier, but then it’s between the Phosphate or Alkalinity checker.

Which would people favour?

Both are good easy and fast.

I would get the alk and phosphate checkers before the HR nitrate, but that's just me. I'm trying to burn through a red sea nitrate kit before I upgrade to the HR Hanna.

The Hanna phosphate checker is the best one to get in my opinion. Then for me it would be a toss up for the nitrate or alkalinity. They're both easy to use, but for those two parameters you can buy other test kits that work well.

I love my Hanna HR checker, got it over the summer and usually check biweekly along with using a salifert as a backup (not 100% ready to rely on digital only). Easy enough, quick enough for me.

Hanna N03 HR, it is very easy to use. I am currently using it every 3 or so days while I lower my N03 in my tank.

I love my Hannas

Well, I Just got tired of trying to read colors of the Tropic Marin nitrate test. I pulled the trigger on the Hanna Hi-Range 782 checker yesterday, it should be here next week.
SaltwaterAquarium.com has a month long promotion this November. I got 1000 points in the give away, so $10 bucks off was enough to sway me into ordering it.

I wish i would have known this before I bought the LR checker the other day. WOW what a pain.

Update...
Well, I just got tired of trying to read the colors of the Tropic Marin nitrate test.
A few days ago I received the Hanna Hi-Range 782 checker. If you have the Hanna 736 Phosphorus checker or the Hanna 774 Phospate checker the procedures to do a test are very similar. The Hanna Hi-Range 782 checker has a 7-minute count-down instead of the 3-minute countdown timer. Like all the Hanna checker packets, cut along the dotted line to open, that seems like a small thing but it makes pouring the reagent out much simpler.
I'm so happy I bought the Hanna Hi-Range 782, no more color guesswork. What I thought were Nitrates between 5 & 10 were actually at 39 ppm!
I'm confident my reef-keeping skills will improve with this tool......
