Hi there, for those of you who use this test kit, when I check for nitrates, you have to shake vigirously for 1 min after adding the #2 solution, I find my caps dont seal and when im done shaking I sometimes only have half the amount of fluid left in there that im suppose to have... is this a common problem, do I shake less vigirous? does it alter the results do you think?
Thanks for your help in advance
