Ammonia test 6.23.13


I have trouble reading the ammonia API test kit.  These don't look entirely green to me (.25ppm) but they don't look yellow either.  In all 3 pix below, the tube on the left is tank water.  The tube on the right is water straight from the tap.

To me, these both look yellowish-green, somewhere between 0 and .25ppm.  

Photo taken outside in natural light, no flash.

Same tests, photographed inside a couple mins later.  No flash used on this or the next pic.

Same test, different angle.
