Nitrates Test kits and monitors!!!!!

[24storm]

I hate test kits!!!

I have a Elos nitrate kit and its show a yellow orange as zero lite pink is 5 and as the pink gets darker the higher the nitrates you have. So i test and i get like an orange kinda color so what does that mean? Is that zero is that less than 5? I hate test kits.

I have a Pin point nitrate monitor. I recalibrate my meter and it says i have between 8 and 10 it changes every couple of minutes. Its a pin point monitor that i bought about a year ago. But i just got a brand new probe for it about a month ago direct from pin point.

Any thoughts?
