It's well-known that the zeolite stones used in the Zeovit method adsorb potassium from seawater. Korallen-Zucht, of course, makes no mention of that in their official Zeovit guide, and instead claims the following:

This is a false statement, correct? Can one particular design of protein skimmer cannot selectively target any element or particulate more than another design? Or is it possible that KZ has a line of magic venturi skimmers?
We would like to point out that it is our thought that needle wheels may precipitate certain elements and destroy plankton. These elements, e.g. such as potassium, will need to be re-added to the system. Do not use a skimmer that is too oversized or employ wet skimming if you use a needle wheel skimmer. We recommend the use of venturi type skimmers.
