Drop Checker solution

[maxwellag]

I got a drop checker and some solution. I was curious what I need to get the drop checker working.
What kind of solution is this? What amounts and stuff do I add?

Did you get that from fort? I'm not sure, but he might have replaced its original contents with some plain ole bromethyl blue. You need 4dkh solution, and a color indicator. API pH test solution works well. If that's bromethyl blue, it's the same stuff as the API pH test.

Yeah its from fort. He said I need to fill it with rdkh and add 5-10 drops of that solution. Thanks
