Salifert Iodine Test Kit

This test kit is not very hard to do. However, it is very time sensitive. A few steps you only have a few seconds to complete.

The results of the test kit can be very difficult to read. It seems the more time you take to make up your mind, the darker the reagent gets, messing you up more.

I no longer bother to add or test for Iodine in my systems.
