ADA Brighty K

ADA Brighty K is a liquid potassium supplement formulated specifically for the ADA Nature Aquarium fertilisation system. In CO2-injected, high-light planted tanks, potassium is consumed very rapidly by fast-growing stem plants such as Rotala, Ludwigia, and Hygrophila. Brighty K replenishes this potassium daily to prevent the characteristic pinholes and yellowing that signal deficiency.

Designed for daily application as part of the ADA morning dosing routine, it complements the Green Brighty Step fertilisers which handle iron and other trace elements. The formula does not contain nitrogen or phosphorus, preventing unintended macronutrient imbalances.

Brighty K is a staple product in competition aquascaping setups where ADA substrates and CO2 systems are used together.
