I am not sure what that color is in the chart. Looks like 0.5, but way darker than chart or maybe it is 1.0. Anyway API paper says phosphate should be at 0, should I use a phosphate reducer?
On another note, also got a new ammonia test because the old one always showed the same result and i'm finally at ease knowing it was the test and now my water coming with ammonia:
