Korallen-Zucht Kaliumtest

[kwirky]

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...
