Hyposalinity in main tank for ich?

[LCDRDATA]

Despite being quarantined and disease free for a month in the main tank, our sharknose goby has developed an ich infestation and is extraordinarily adept at sensing anything with which we might capture her for transfer to a hospital tank. Our water parameters are otherwise all good, and no other fish (with the possible exception of a Randall's shrimp goby) are currently affected. I'd like to try dropping the salinity (in case she continues to elude us) to at least slow the ich down and hope she can get better on her own - having previously killed off much of a tank with a "reef safe" treatment. My question is, considering the corals, clam, shrimp, and various other desirable inverts, how low can I drop the salinity, and how fast, to impact the ich without major negative effects on everything else? I normally maintain a salinity of ~1.026. Thanks!

Unfortunately, you cannot lower the salinity enough to damage the ich without killing your ornamental invertebrates. Don't try, it won't work. As you already know, the 'reef safe' treatments also do not work. Before you do anything, make sure it is ich and not microbubbles or sand.

If it is ich, all of your fish have been exposed and there is a good chance they have some level of infection, visible or otherwise.

If you want to rid your tank of the parasite that causes ich, you will have to remove every single fish in your tank, put them in a hospital tank, and treat them with the method of your choice. I like Cupramine. While they are being treated leave your DT completely fishless for 8 weeks as the parasite will die in that time with no fish to host in. After that, your DT will be ich free and you can put properly quarantined fish in without worry.

i just notice ich in my tank this morning and all my fishes have it (yellow tang, 2 clowns, six line) could i just rid it in my DT? i have another tank that is cycling and im going to transfer them in there after its ready which is very very soon. coould i just treat them in the tank they are in rite now and just move them to the new tank when the ich is gone?
