ADA Brighty K (Potassium) ADA Brighty K is a fertiliser designed for planted aquariums to provide potassium. Potassium deficiencies are usually indicated by yellowing of leaves meaning the photosynthesis and growth of aquarium plants are affected, the plants also have a lower resistance to algae so algae can take over. Using Brighty K daily promotes the growth to help resolve the above issues. ADA Brighty K also has buffering capabilities to prevent a decline in PH of the aquarium water. The pH of aquarium water may rise temporarily immediately after this product is applied, but it will eventually return to the original level, due to the product being strong alkaline.
