I’ve been using this magnesium solution for three months in my 120-liter reef tank. The water stability has improved noticeably, and my corals have shown better color and growth. Easy to measure and mixes well with the rest of the care system.

After switching from a generic magnesium supplement, I noticed less algae growth and healthier polyps. The balance with calcium and strontium in the system feels much more natural.
