Brightwell Aquatics | ChaetoGro

ChaetoGro by Brightwell Aquatics is a carefully balanced supplement created to enhance the growth and vitality of Chaetomorpha and other macroalgae commonly used in display & nutrient export systems.

Formulated without nitrate or phosphate, it’s ideal for ultra-low nutrient tanks and works as a trace-element fertilizer for display macroalgae. Instead of overloading the system, ChaetoGro supplies 13 essential elements—including potassium, iron, magnesium, boron, sulfur, and zinc—that macroalgae need for healthy development, efficient photosynthesis, and strong cellular function.
