Yeah- phosphorus ULR is a definite.
Not too worried about the test itself- I do analytical biochemistry as part of my job and a lot of the caveats people are mentioning in YouTube tutorials about accuracy and handling are standard operating procedure in a lab.
Think I’ve narrowed it down to -
Alk dKh
Phosphorus ULR
Calcium
Copper (for hospital tank) - unless I can convince my vet to get chloroquine phosphate

The alkalinity Hanna Checker is great.
I use the Hanna Checker for copper in my QT system. I personally will never run QT without it. I like knowing that the copper is at a safe and effective concentration and I really dislike all the color change copper test kits.
I also use the Hanna Checker Calcium. People seem to hate that one but it's been great for me. Precise across many checks and accurate against my Red Sea Calcium kit.

Phoshorous ULR is the only one that is a must-have. You can use these for alk and calcium, but Salifert and/or RedSead (or whatever) are also very accurate and easy to use and probably cheaper in the long run. I test alk about every day and I can do it in less than a minute with taking all of the stuff out of the box, testing and then cleaning and putting it all away.
As long as you get the ULR Phosphorous, you cannot go wrong here. Nobody can get even close to this test kit.
Edit: when using the ULR, wipe the vials clean with a soft cotton cloth and be sure and wait the three minutes before you measure. The color will shift over the first few minutes, so you want to always have the same timeframe for your check. There is a three minute timer on the checker if you want to use it. I get very consistent results if I make sure that the vials are clean and use the same time intervals.

I totally had a brain lapse. You're right. I was thinking there was a ULR and HR copper checker. Looks like there's only the HR. It will measure the low Cuprion @ 0.20ppm all the way to the higher ionic @ 2.0ppm.
