I just ordered a Hanna copper test kit. I'm still torn on what to do with the mandarin I got him eating frozen and he seems to be doing great I'd hate to lose him in the copper treatment. I have a QT it's not setup at the moment. To set it up as soon as possible is it acceptable to transfer 10g of water from my DT to my QT so the temp and salinity is perfect and then just add copper to that. Do I need to acclimate fish if I decide to go with brand new mixed saltwater or do I just drop the right in? Another problem is I habe a vacation planned and I leave the morning of May 7th. I don't have the 76 days to fallow the DT before I leave and I don't have another established tank with a bio filter to move them to while I wait for the DT to eradicate the Ich. Also how long do I treat with copper for? Is it 14 days from the time of no symptoms? Or just do 30 days of copper treatment flat.Well my mandarin and clownfish pair have been good I've hardly seen anything on the mandarin and haven't seen a single thing on the clowns. Just woke up and the Gramma isn't doing well unfortunately I don't think he's gonna make it through the day. I have some copper power on hand I don't have a copper tester on hand yet however. What about hyposalinity I heard that works for Ich? And the mandarin maybe able to handle that?
