Salifert Potassium Reef Test Tunze Exhaustion is indicated by aPotassium concentration in natural seawater is approximately 400 ppm. Many aquarists have reported that a low potassium value reduces colors in corals. This can be corrected by increasing the potassium value to the normal natural concentration. Now you can accurately measure this value with the new Salifert Potassium Reef Test kits. Test resolution of 10ppm ranging from 0 to > 470ppm.
