Korallen-Zucht Kaliumtest

Heh

So do you guys test regularly for K+? They seem to place a lot of emphasis on it on the Zeovit forum.

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.

step 1: pack everything up into the box
step 2: throw in garbage lol (don't tell dennis I said this!)

lol I'm a little biased on this one but I think the potassium testkits are VERY hard to use to the point where I just don't test it. I know the big bottle is distilled water but does anyone know what the little dropper bottle contains? If so one could do a proper precipitate test with a little chemistry math and a lab quality scale.

I remember back in chemistry with this type of test you're supposed to be working with large enough volumes that you can filter out and weigh the precipitate (we used coffee filters on our high school lab scales).

Guessing the approximate value through a colour chart is technically the wrong way to measure this kind of precipitate I think. Unfortunately lab style testing is out of reach of us hobbyists...
