Just for your info, I used a 10 gallon bare aquarium, 50w heater, hang on back filter, an air stone, and 4" pvc
cut up on the bottom to give them a place to hide (don't use substrate on the bottom).
I used CopperSafe chelated copper with an API copper test kit. Daily topoffs to replace evaporation.
Please do a bunch of research before deciding on any treatment and ask people at your LFS
There are also other methods to try like freshwater dips, hyposalinity, increased temp, other medications, vitamin/garlic supplementation, antibiotics, and combinations of these. Read about them to see if you would like to try them. But from what I understand, copper and a fishless DT is the best bet to get rid of it. QT and coral dipping is the best way to prevent it.
