Does anyone have trouble differentiating between 2.0 and 4.0ppm on the color card? It's a bit hard for me to tell what color it is exactly on the card.
API ammonia test question

it can get tricky with those shades, but ultimately, i'm hoping you are just cycling, b/c the difference between 2.0 and 4.0 ammonia is only helpful in that kind of situation. 2.0 or 4.0 will kill either way
take the card and tube outside and check it in the sun.. its a lot easyer to tell in bright light
i agree. i usually will take it to a window and get the bright sunlight on it.chesterthehero;3351484; said:
I'm cycling and using an API test kit too! The ammonia card is a bit of a pain, but I'm not too worried about it becuase I only really need to know when it hits 1ppm.
The one that bugs me is the nitrite card. The last three colours are purple pink purple!!!!
I'll have to try checking it in sunlight though..

Yeah seriously 
I don't use the ammonia/nitrite card much. basically if ammonia shows anything then I know the cycle has started. Then after a few days I check nitrites, if it shows something then great on to nitrates if not then wait till it spikes.
Now the Nitrate card is dumb. The last three or four are all shades of red. The 20 and 40ppm colors I can never tell the diff. Maybe going outside will help.

When I get to nitrates, I'll probably just do a water change when it hits 20 to make my life easier, lol.
