Manganum is a concentrated manganese supplement designed specifically for saltwater reef aquariums. It plays a critical role in metabolic processes and photosynthesis, ensuring proper nutrition for corals and other marine life. Each milliliter of this solution increases the manganese level by 0.001 mg/l per 100 liters of water, with recommended levels ranging from 0.001 to 0.0022 mg/l. Manganum is ideal for maintaining optimal environmental conditions that closely mimic natural seawater.
