Hagen Nitrate regent #3 Chunks?
Hey all, I have a quick question.
I just bought a Hagen Nitrate test kit, which is all they have at my lfs, and it says to shake #3 bottle vigorously for a little bit. Well I shook the living daylights out of it and it still seems to have little chunks in it, and the drops are hard to get out now because it gets clogged with those chunks.
The expiration date says it’s good till the end of this year.
Also it seems to read wrong, I started to dose my nitrates and it still reads zero, and I'm dosing for 10ppm...
Any help would be awesome, that’s all you out there.
