Help. I have been treating my angelfish for a little over a week in a mild salt water bath in my quarantine tank (1 tsp/gal of water). I now need to move him back into my main tank. I have read a 30% water change and wait a week. then another 30% water change with another week. Does anyone have any input on this? Is it necessary to wait so long in between water changes or can i just acclimate him in a day or two with water changes then reintroduce him to my main aquarium? Thanks for all your help!
