## Description

Hanna Calcium Reagents, 25 ct. for use with Hanna HI758 Marine Calcium Checker

Review: OEM replacement reagents at a great price - These replacement reagents are a necessity if you plan to keep using your Hanna tester. Best price I could find on the internet. Does not come with the digital tester or test tubes - this is just the replacement reagent. The one I received had an expiration date 18 months from now which is way longer than I need but great for people who only have one tank or who test less frequently.
Review: Hannah calcium - Works great will buy again
