A conversation with a Hagen rep found that regent bottle 3 if
frozen seperates the zinc from solution. once seperated the test
is worthless. When ever the regent is seperated for any reason
the test wont work... At that time he did not have a answer for the fix.

We foud that our kits were getting frozen in transport way befor we got
them.
Time to look for a different kit>>>hth

I think the only way they can prevent that from happening is to provide
reagent 3 in dry form, as Seachem does with their NO3 reagent. Until then,
I'll be using the Seachem kit.
