You are looking for a sign of life, but instead, you see a patch of white upon your prize Acropora. Your heart sinks. I have spent thousands of dollars on high-end lighting, flow patterns that mimic the Indonesian coast, and the most costly skimmers child support can buy. Yet, for months, I struggled afterward the most basic element of reef tank chemistry. I could not save my magnesium levels stable. I was guessing. I was "eyeballing" my liquid magnesium doses based upon vague forum posts. It was a recipe for disaster. That is until I finally leaned into a tool I had ignored for far-off too long.

I was wrong.
