Have you read this thread? I guess I don't understand why you feel the need to add even more confusion for this young lady. All of this isn't information that will help her with what is going on right now and will just confuse her more.A little more info, higher pH and temp make ammonia more toxic. Some fish give off more waste, I.e. more ammonia. Lots of variables. Ammonia of 2ppm in 72° with pH of 6.8 would be fine, 2ppm at 79° and pH of 8.0 would likely kill any fish.
