Doktorfisch Additive Potassium

Additive K:

Doktorfisch Additive Potassium is a highly concentrated potassium solution designed for marine aquariums to specifically compensate for potassium deficiencies. A stable potassium level promotes the health and color intensity of the animals. Even a 5% drop can significantly impair the growth and coloration of corals.

Dosage:

10 ml per 100 liters of seawater increases the potassium level by 10 mg/l.

Shake well before use.
