ChaetoGro by Brightwell Aquatics is a complete multi-nutrient supplement designed to support the growth of chaetomorpha algae in marine and ultra-low nutrient systems. It provides essential iron, cobalt, molybdenum, and other critical elements that are necessary for long-term health, vibrant coloration, and robust growth of aquatic plants without contributing phosphates or nitrates. This supplement is particularly well-suited for those maintaining ULNS aquariums as it aids in nutrient control by enhancing the uptake of unwanted nutrients like phosphates and nitrates through chaetomorpha.
