Most accurate Nitrate & Alk tester recommendations

What are you using to test Alk and Nitrates?

Looking for the best and most accurate.

Considering

Red Sea for Nitrate
& Hanna for Alk.

Any suggestions?

Tank.
Red Sea Max 130 34 gal
5 fish & mixed lps & sps.

 

I concur with your consideration
that is exactly what I run

 

Note that your lab skills often matter more than the test kit.
Always clean everything with RODI.
Do you know what meniscus is and why it matters?
Doing drops....

IMO: Best Alk test is this one:

Especially if you test a fairly large volume of water.
Not as hard as it seems

That said : I never bother with anything fancy. Chasing numbers ...
