I purchased a testing kit that uses 4 vials - tests the usuals - ph, nitrate, nitrite and ammonia.
The directions say to examine the color after 5 minutes.
After 5 minutes the water is one color - but it seems that if I leave the vial on the countertop, and examine the color again in, let's say, a half an hour, the colors deepen and it suggests higher levels.
Do the colors become inaccurate after they sit for a prolonged time?
