Potassium Test Kits ?
Just wondering if any one else has trouble reading the results of the Korallen-zucht potassium test kit ?
I find it VERY hard to read , to the point that you basically have to guess a result. Which makes me feel that it is a joke.
The first time I tried it, I immediately thought "boy did I ever get sucked in on this one ! "LOL !
Has anyone seen any other brand of potassium test kit ?
