Brighty K is a liquid fertilizer for supplying potassium to planted aquariums. When potassium is insufficient, the photosynthesis activity and growth of aquatic plants are affected, and this can cause yellowing and bleaching of leaves as well as lower resistance to algae. Daily application of Brighty K to the aquarium eliminates these problems caused by potassium deficiency and promotes growth of aquatic plants. Brighty K also has an effect of enhancing the buffering capacity of water and prevents a decline in pH of aquarium water.
