8months ago, i used the api ammonia/ammonium test kit to test my discus tank , the result is red LOL. Around 80ppm?? Its high. But my discus still v.happy and yet discus is known to be 1 of the most sensitive fish in fw. No casualties since ph is less than 7 in fw. If its above 7, all will convert to ammonia then gg liao haha
