Hanna checker

start with the first, then buy the second, then the third.

The real answer depends on your situation and what you are working on / struggling with.

I like the 774 phosphate checker
I also like the copper checker for my QT setup.
I used the calcium checker twice and I really do not like it. My salifert kit is much better imo.

Personally I don't see a reason to invest in the other checkers (ph, dkh, nitrate). I say personally because my levels are stable enough and my existing test kits work just as well as a checker would (I only look for extremes, I try really hard not chase exact #'s).
 
I went with:

1-salinity checker
2-phosphate ULR
3-alk
4-calcium

I think thats all I need for now for Hanna
 
1) Alk HI772
2) Phosphorus ulr HI736 or phosphate ulr HI774
3) Nitrate HR HI782
 
If I have to be honest I’m not a big fan of the salinity checker. I prefer old school hydrometer I feel it’s more accurate and you don’t have to Calibrate it after ever couple uses.
