Brighty K is a potassium-rich formula designed to strengthen plants and increase plant growth.

Unlike nitrogen and phosphorous which are produced in a planted aquarium， potassium tends to be scarce.

Brighty K provides an instant source of potassium to help produce the right balance of nutrients for optimum plant growth and strengthened roots and stems.

In addition to this， regular dosage of Brighty K at water change can neutralize chlorine in tap water.

Also available in 250ml & 500ml.
