Mag Checker Update

Hanna MAGNESIUM CHECKER Update - Mr. Saltwater Tank - Raw, Uncut, and First Impressions

In this episode of our series, Mr. Saltwater Tank - Raw, Uncut, and First Impressions (RUF), Mark will revisit the Hanna Instruments Magnesium checker. Why are we looking at this again? Because Hanna has acknowledged the issues and narrowed down the problem to its reagents they have since replaced. We'll test this checker again to review its use and see what has changed. Will we get an accurate reading this time? Find out!
