For those who are better at chemistry than I am:

I have just purchased some Formalex Green to neutralize our waste 10% formalin 
for safe drain disposal.  I noticed that I can also purchase a test kit that 
will tell me if the aldehydes are safely neutralized.  Instead of that, 
couldn't I just add a drop of Schiff's reagent to the final product, and that 
would indicate if there are any unreacted aldehydes?

Thank you in advance,

What does your state require? New Hampshire requires to test with the test kit 
and if at zero we can drain dispose. The state also requires us to keep our 
test records for five years.
