Hypo salinity treatment for DT

[redlac]

Hi
Could someone tell me how to start hypo salinity treatment in my 350l DT. I foolishly do not have a QT and a couple of my fish now have whitespot, fire back angel and a couple of yellow tIl damsels. I have a blue cleaner wrasse who is doing his best to clean them. Have read that this is probably my only option without a QT. I have a UV light in my filter. Starting to get a bit desperate now.
Thanks

I wouldn't do any treatment in a DT as you will have to treat the fish unnecessarily long that way.
If you treat in a QT you can have the fish disease free in 2 to 4 weeks (depending on the chosen treatment). In the DT you would need to treat for up to 11 weeks and that could be harmful for fish.

As I understand, Petco will have its $1/gallon sale soon and I would strongly recommend to pick up a couple of 10 and 20 gallon tanks for quarantine and treatment.

As a quick solution you could also use a clear plastic container with enough volume.
