This water conditioner is designed to improve fish and shrimp spawning and help aquatic plants absorb trace elements through chelation. Its safe ingredient slightly reduces the tank's pH level, making it ideal for South American fish and aquatic plants that thrive in weakly acidic water. It contains humic acid, fulvic acid, and trace elements commonly found in black water, which are beneficial for tropical fish and plants. For optimal use, add 10 ml (1 cap = 5 ml) of this product per 10 gallons. For a lower pH, usage can be increased.
