QT tank full of ammonia

[ReefGeekCanada]

I put my coral beauty into QT becasue it developed one cloudy eye.
The QT tank is a 10g with no biological filter. I dosed the little tank with AP Erythromycin (which would've kill any biological filtration...)

I went through a full box of Erythromycin but he actually got worse. his tail developed a little whole in it.

One of the problems was I couldn't keep the ammonia down. I did a 50% water change every other day like the box said and still I had 2ppm ammonia.

How do you use antibiotics and keep the tank water chemistry clean and free of ammonia?

Was that medication correct for one cloudy and slightly popping eye?

my cardinal has one cloudy eye and one popping eye also. i am not sure what to do. i put him in a 10g qt been trying to give a liquid medicine but he won't take it. his right eye is bad. sorry i am not sure what to do but sounds like our fish have the same problem

I decided to put him on ice tonight. Its been a week in a high ammonia QT. No more suffering.
I think I'll do a necropsy tomorrow in my Bio class. I love finding the swim bladder if you can keep it full of air.

The antibiotic I used was a power to be dissolved in the tank. He didn't have to eat it...
