Nitrate +
Contains concentrated nitrate to add to depleted nitrate to ultra-low nutrient systems (ULNS). Many issues can occur in ULNS, for example, loss in coral color or bleaching, fatigued coral, and slow growth from nutrient deficiency. Adding nutrients back into a ULNS will increase the zooxanthellae population. Overdosing will cause unwanted algae growth.
2 drops (0.1ml) will raise 100L of aquarium water by 0.1 ppm.
