Reading of DD test kit - Nitrate

[nicreef]

Just got a DD nitrate test kit. used the low range and abit lost on how to take the reading.

comparison to 2 - 4ppm (lighter than the red shown so should be lower?)

Comparison to lower than 1ppm chart - standard on the right. tank water with reagent on the left . (doesnt really match any).

haven't tested it on the other reading coz i ran out of di water.

Should not be orange color. Try to shake your test kit bottle before dripping and try taking it again. If not can find reef depot since they are supplier. So far my set I use never get this color before. And wait for 10 mins and after 13 mins result not accurate as what the instructions say.
