I made ~1L of 4dkH solution on 3/19/2013, and I'm pretty excited when I knew the drop checker ordered 3 weeks ago arrived today (ship from Hong Kong).
Surprisingly the package come with a indicator, I thought it is a plus.
Then I tried to set the DC up. Fluid refused to get pass the narrow neck of the DC... solved using a plastic transfer pipettes.
Rinsed the DC with 4dkH well before dropping the indicator (with the cheap one from eBay). The color turns GREEN.

I am at a bit of an impasse; I really cannot find a reasonable way of efficiently chelating individual metals with “household” items.
So far the recipes seem to be working well, they really are not for “dry dosing,” but work well mixed in a slightly acidic solution (<pH 5), either as a stock solution or as the “dry dose” amount and mixing (distilled water is best) it prior to dosing.
A little vinegar (acetic acid), lemon juice, Vitamin C (ascorbic acid) anything
