Oh great, I've got some of that, might as well order a 100ml bottle of 4dkh for the same price as the mixed smaller bottle :D How many drops of Bromo blue do you put in the drop checker with the 4dkh?

personally i put 3 but you can put 2 to 5, 2 being a lighter colour and 5 a more intense colour, i like it somewhere in the middle.

I've got 3/4 bottle of 4dkh and 3/4 bottle of bromo blue in the cupboard if you're interested? A couple of years old but I've no need for it now. Drop me a PM and I'll check it is still there.

The solution in the first post is reference solution. Not what you want. It is for the drop checkers that have 2 compartments.

1 for your 4dKH solution and then this goes in the other one. It is to see a comparie the colour between the reference (linked in first post) and your actual reading.
