So, I have a brand new Red Sea pro NO3 test kit. I have probably tested with it 5 or 6 occasions doubling up on the tests on some of them.
Exp date is late 2018, so I think Im good there. I follow the instructions and measurements exactly, I actually use a stopwatch to time each step including the agitation of the reagents.
Every time I end up with a little bit of what I can only describe as precipitate (sp?) of the powders in the final solution after waiting the required 9 minutes...
I make sure it is all shaken and mixed well before the 9 minute wait time. But each time there is some little dark colored "clumps" floating around in the vial when it comes time to read the results.
Is this normal? Or is it messing up my readings on my tests? I am having a bit of a PO4 jump in my tank due to dosing the Fluconazole and all my equipment offline, but the No3 hasn't risen at all according to this test kit.
Thanks for any help you may have.
