Ive also tryed doing extra water changes but still nothing different. I've had my water tested at my fish store and they get the same readings. I used test strips that said i always had between .25 to .5 ppm. Ammonia has an odor threshold ranging from 1 to 5 ppm.

But, when one is cycling a tank with fish in it, we tell people that .25 is the level of ammonia that is considered to be safe. You must have SOME ammonia to cycle a tank. So, .25 is sort of a compromise between the ideal of zero and more than .25. Not perfect, but not a disaster.

ammonia level was 32 ppm for only 7 d or 10 ppm or less for 28 d. Therefore, our data suggest that for mice housed in IVC, which have the potential for 24-h exposure to ammonia for days or weeks at a time, intracage ammonia levels should remain below 25 ppm.” (reference: Vogelweid C.M. et al. 2011.

this morning my parameters are as follows Ammonia 0 Nitrite 0.50 Nitrate 5.0 PH 6.8 Going to do water change now At a pH of 7.4 any API test reading for Ammonia will actually be 99.99% Ammonium, which is harmless to fish. Same for tap water Ammonia levels. If gassed out pH level of tap water is 7.4 to 7.6 the Ammonia reading is again actually about 99.99% harmless Ammonium. To find the values of m and b we have to consider two points (x1,y1) and (x2,y2) on our gas line. Here we are working with ammonia so the two points I have considered is (40,1) and (100,0.8) as shown in the picture above (marked as red) with red marking. m = [log(y2) - log(y1)] / [log(x2) - log(x1)] m = log(0.8/1) / log(100/40) m = -0.243 My ammonia started at 0.25-1.0 ppm for the first couple of months .
