We have every been there. It is 2:00 AM, and you are staring into the deep blue exhilaration of your SPS Reef Tank following a flashlight. You are looking for a sign of life, but instead, you look a patch of white upon your prize Acropora. Your heart sinks. I have spent thousands of dollars upon high-end lighting, flow patterns that mimic the Indonesian coast, and the most expensive skimmers allowance can buy. Yet, for months, I struggled as soon as the most basic element of reef tank chemistry. I could not keep my magnesium levels stable. I was guessing. I was "eyeballing" my liquid magnesium doses based upon distant forum posts. It was a recipe for disaster. That is until I finally leaned into a tool I had ignored for far too long. This is my honest, slightly chaotic, and ultimately well-to-do version of My Personal Experience taking into consideration The BRS Magnesium Calculator For My SPS Reef Tank.

Lets be real for a second. Most of us obsess more than alkalinity and calcium. We treat them afterward the king and queen of the aquarium gallon size calculator. We check them daily. We have high-tech dosing pumps dedicated to them. But magnesium? Magnesium is often the forgotten middle child. I used to think as long as the exam kit didn't viewpoint sure immediately, I was fine.
