BRIGHTY K is a liquid fertilizer supplying potassium to a planted aquarium. 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 improves these problems and promotes the healthy growth of aquatic plants. BRIGHTY K also has an effect of enhancing the buffering capacity of water and prevents a decline in the pH of aquarium water.
For supplementation of potassium, apply one push (1ml) of BRIGHTY K for every 20l of aquarium water daily. It is effective to add GREEN BRIGHTY K when the lighting is ON. If there is a large number of aquatic plants in the tank, increase the amount to approximately 2-3 times the standard dose.
