High Ammonia in QT

[zibnata]

I set up 20 gallon QT about 10 days ago.Treated tank with maracyn-2 for 5 days for hippo with a cloudy eye.Hippo looks great now.Started hypo a few days ago for ich.I have been doing small water changes every couple of days.I noticed red streaks on yellow tang. I just checked ammonia and it is at 1.0. I just did a 5 gallon water change with saltwater I mixed up last week.I am trying to feed alot to keep them healthy but could that be cause of ammonia ? there is a hippo,yellow tang,blackcap basslet,blue devil damsil and royal gramma. What should I do about the yellow tang,maracyn-2 again ? Should I use diluted display tank water for water changes ? Thanks

the cause of the ammonia could be that your QT tank is cycling.

nitrates are 20. I used display tank water to fill it so I didnt think it would cycle.Although I have used fresh water to drop salinity down to 1.009.What should I do ? This whole thing is getting frustrating.thanks

what kind of filtration are you using on the QT

a penguin power filter with a biowheel and carbon filter

Does anyone know what I should do ? Are the fish in danger?
