Salifert Potassium Reef Test

Potassium 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.

The Potassium test can be performed in about 90 seconds. This tritatic test kit has a sharp color change, going from yellow to blue, when you hit the level in the sample.

This kit is good for 40 tests.
