I have just done two nitrate tests on my reef aquarium. One (Red Sea)

25 ppm the other (Aquarium Pharmaceuticals) said 15 ppm - both are too

I know but the difference in kits and the result interpretation issues
make
them difficult and time consuming to use.

Anyone know of any accurate and quick kits?

LaMotte is supposedly very accurate, but I've never shelled out for one
so I don't know how fast it is. My Seachem kit has a 10 ppm standard
you can run to compare, but it's slow and the dropper bottle for one of
the reagents is difficult to use - hard to get a the required single drop.

Ahh, those dropper bottles. I keep getting bubbles of reagent issuing
forth instead of a complete drop of reagent. The bubble-drop then bursts
and random amounts of reagent drop into the sample. Means restarting
with fresh sample.
