Is that with 16 ml of tank water?
I am wondering if the regents are reacting to something in your tank... Maybe that is your issue? I would test a sample of Rodi water to see what happens.
The bottle in the middle is your test sample and the one near the edge is just tank water. You spin the wheel until the colors match just like you said.

Did you try the Red Sea kit on Rodi water? Just curious if it would be clear.
