Review on 🔬 Accurate Measurement of Nitrate (NO3) Levels: NYOS Reefer Aquarium Test Kit by Shannon Williams

I have been using this kit for a few months now. As one of the other reviewers mentioned, the dropper bottle is probably the worst dropper bottle I've ever used. The one that was in my kit drips out when the bottle is inverted without squeezing the bottle. You have to be very careful with it. The droplets also appear to have turned a light yellow hue, which will immediately stain your test sample. I'm not 100% sure but I think the drops were clear when I first received the test kit. The rest of the kit is good. I like the little sample bottles and the color chart. The piece of styrofoam holding the two tubes should be pressed more firmly against the tubes. I've spilled them a few times trying to pick them up by the foam, although I know that wasn't meant for that. As far as testability goes, that's good. - 2 stars for a bad dropper bottle.
