I'm in the process of setting up a 30 gallon hospital tank. Does anyone have any suggestions. I'm not trying to do anything fancy just a few pieces of live rock. I plan on treating the water with copper so I can move my fish from my 72 gallon reef tank in there. They seem to be infected with a parasite. I also want to keep it up and running to use as a quarantine tank when adding new fish. What is the best level to keep the copper at? Do I need to add a protein skimmer to the tank or would that effect the copper levels. I'm kind of new to saltwater fishkeeping so any help is appreciated.
