Korallen-Zucht Kaliumtest

[Delphinus]

I tested the heck out of it for about 2 weeks, then gave up because in the end because I felt I was just guessing too much at the final value. (ie. "Yeah, I guess I can't see the colour strip anymore.") I figure if I can maybe get with someone else and we both try reading the same samples and we both get similar guesses then maybe I'd start up again. Basically I need a reference of some kind, either a known sample or at least an external confirmation that my results are close.

If this were a perfect world, I'd aim to test the value on a weekly (or thereabouts) basis. I don't like it when I get my tests too far apart in time (doesn't mean I'm very good at it) but my goal is to have a baseline done about once per week.
