OK so I got a 120 gallon tank that is infested with Ich my fish spent 8 weeks total in quarantine/ hypo. the last three weeks they showed Zero ich. now about a 3 daysafter being in the DT they agian are breaking out with ICH. FML ok so i intend to check my parameters. I Imagine all parameters are at ok levels the fish are all still eating very hearty. I assume I will end up removing the fish from the display tank and starting over with hypo. My yellow tang id showing the most spots and has the been ideling in the corner and ocasionaly scrating on rocks. I will be leaving a stingray in the tank only option. assuming 8 weeks fallow without fish in the tank. I can only assume that i will have to leave it empty for 10 weeks. Does anybody have any thoughts on what i could do. I have a small QT tank 29 gallons i can attempt copper in a ten gallon i own however the size of fish will really be hard to keep them without stress and i prefer not to put copper in my 29. i was thinking maybe put the ray in the 29 with a fat sand bed and hypo the DT. I know i would have to remove the sandbed but how will my rocks fair and how hard will it be to keep amonia down. Ill tell you im ready to be done with keeping fish i have had a hard time with salt and tried to do everything according to the books but it seems i keep missing some steps somewhere.
