I’m using ULR phosphorus.
I preformed 2 tests back to back with same vial and I got .443 and .438 phosphates. My red sea phosphate test was in between .08 and .12
My tank appears to match the red sea test. Not that much algae except on the power heads.
My Hannah used to test 0.03 last week.
Anyway, I have 2 vials which I use in rotation (never both vials for the same test). I forgot to clean the last test so it’s been sitting in the vial. I rinsed the vial with soap and water. The other vial had vinegar in the vial if I remember correctly. I don't remember which vial I used, but I used the same vial twice and I got the same result.
Then I tested with a vial from my Hannah alk test kit which was used for the alk solution. I got a result of .40 which is slightly less.
I clean my vials by rinsing in tap water and closing the vials with a little tap that remained after me shaking the water out of the vial.
As far as test procedure, I preform is super accurately. I shake for 2 minutes. Use same vial for entire test. Tap bag to get powder out of edges and make a funnel. I wipe down the vials before each reading C reading. I am pretty confident in my ability to preforming the test, but I’m not confident in my ability of washing the vials.
One thing about Red Sea is that it’s pretty bullet proof. There’s no potential air bubbles or fingerprints that can stain results. I use the tap water to clean the Red Sea vials like with the Hannah checker. I also have more confidence in my ability to tell colors apart vs a colorimeter with no calibration.
So why don’t I just stick with the Red Sea? Because I like to use multiple test kits to ensure I’m not having a test kit inaccuracy. It prevents me from making a drastic change. For example, today I used hannah and not the Red Sea. If I didn’t double check the hannah twice, and then with the Red Sea, I would simply overdose my tank with chemicals which woukd starve my tank of essential nutrients.
That’s why I’m bothered inside. Maybe the hannah IS accurate and Red Sea isn’t? Uchh. How can I know?
For phosphate I use hannah and red sea
Alk: hannah and red sea
Cal, mag, nitrate, I use Red Sea and salifert
As you can see, I have different brands to double check results because I’m weird like that. So far I really like my Red Sea test kits the most. Except I feel like the nitrate test kit high range doesn’t work because the color turns a different shade altogether. It’s just an incentive for me to keep my nitrates lower so I can use the lower range
