Test kit for alk

Gives Bad Advice.
Should I get another salifert chemical test kit or a Hanna digital checker?

Need to replace that as well as calcium.
Digital is $50 vs 14.99. Shipped next day with prime.
 
I have a Hanna Alk digital and I'm very happy with it, simple and quick to use. I haven't used the Calc but I have also read that they are a pain to use.
 
Hanna for Alk, your most important reading. Whatever for Ca. I use API for Ca cause its cheap, and in only measure it once per month. I know... some API haters out there but for Ca they do the trick just fine.
