I am kind of new to discus keeping and Last time I added Epsom salt I got a reading of 8 ppm ammonia. No idea why..Is this necessarily toxic ammonia? As far as the epsom salt, there is no fragrance or additives. I have checked the package. 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.

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 2017-11-10 · With a higher ammonia concentration ranging from 72–134 ppm, the same irritation can occur in half the time.
