I opened my Sn a week ago and now it is a bit clumpy? Did i screw up?

I wasnt aware you shouldnt open the bottle until immediately before you want to attempt your CTB so i opened the bottle about a week ago. Does the clumpiness - sry if this is not the right word- indicate my SN is not effective anymore?
Not the entire bottle seems to be in clumps, but just the top half, the lower half seems fine

Under the influence of oxygen nitrite is converts into nitrate, which is no longer usable. This doesn´t happen within a few minutes. But don´t leave it open too long. It´s normal that it is slightly clumpy and slightly yellow. You should do a blood test before you use it. Just mix a few drops of blood with some SN. If it turns brown, it should be ok. Keep some blood to compare the colors.

Whats the max time one could leave it open for?

i opened it a couple of times out of curiosity and ignorance of the fact that it could convert into nitrate, but i never left it open for more then a couple seconds each time.

Better use the search function and read guides, before you order things and use them. "a couple of times".... I think nobody except a laboratory can check how much nitrite converted into nitrate. It wont happen within seconds. Do the blood test before you use it.
