nitrate test results

Recommended Posts

has any one else gotten false positive nitrate results from a red sea kit? I just got one a few weeks ago, an it's been giving me some weird high readings. Some where between 16 and 32 ppm nitrate. The solution is reacting a purple color, not the pink tones of the color wheel, so it's harder to compare. Same results with this kit over the last 2 weeks with 3 wc (2 15g and 1 25g). ive also been testing with a non expired api kit I keep for my fw tank. The api read 20ppm nitrate 2 weeks ago and 5 ish today.

 

The 20ppm reading makes sense. Ive been having issues with my skimmer for months now (but hopefully I finally fixed it. Found filter fuzz from the filter sock in the impeller, and removed it. real bubbles again!!) But trusting the api kit for my reef feels odd.

 

Any ideas? Suggestions on a better test kit option?

I have not used this particular Test kit from Red Sea but have used others, and I notice I get strange readings if i don't "Shake" the reagent before testing. Just a Suggestion. Good Luck!
