This question troubled me over past monthes: I am confused at the result I get from the Salifert test kit for ammonia since different lighting gives different color of the solution:
This is what I get under warm color toned light, comes from water test few minutes ago,looks like 0.15
The same test result under white light, looks like 0 now:
Since 0.1 ammonia can possibly kill fish (I have 10.0 kh so this will get only worse as more ammo exists as NH3, trying to lower it), I want to know what color of light should I put the test kit under to test my result?
