I have a 90g tank set up to QT an orange shoulder tang, bluethroat trigger and one spot foxface. There is an aquaclear 110 running on it, with media seeded from my 150g reef. The trigger is showing ich so I need to treat, but am currently having issues with my ammonia. I've added a sponge filter and have been doing daily %25 water changes. The ammonia stubbornly is staying at 1mg/l (according to 2 seperate api tests). Could my tests be wonky? When I test the reef it's at zero. Why can't I get the ammonia down?
