- Made in Holland
- Approx. 40 Tests
Potassium concentration in natural seawater is approximately 400ppm. Many aquarists have reported that low potassium value reduces colours in corals. This can be corrected in by increasing the potassium value to the normal natural value.
Measures in approx. 10 ppm increments.
