tests are easy to do, Ammonia takes 30 minutes for the more accurate test, though it is simple to do. I always have trouble deciding which color matches best but that would be true of all the brands I have used. Under incandescent lights the nitrite was never 0, I read online for a different kit to read it under natural or florescent light, Sea Chem reads 0 under natural light, if this is the correct procedure it would be nice if it stated in the Sea Chem instructions which are simple and clear.
