Hospital tank set up advice, please comment on plan

[Delphinus]

Hi Paul,

Thanks for the replies.

So no to the Aquaclear then? Just water changes every 2 days in an otherwise filterless tank? Should I add a small powerhead for water movement or find an air pump and air stone?

Do I understand correctly that you recommend both SG down to 1.018 and cupramine at half-dosage for butterflies?

And potentially methylene blue? How do I know if this is needed?

Man .. I am totally out of my depth here.

Here is the the thing: they really don't act as if they have ich. No scratching, no loss of appetite. But they are covered with white dots, they look like they have been salted. This comes and goes. I have a UV on the tank as well but it must be completely ineffective (the lamp needs replacing and it's not one I can get locally - it's an AquaUV 57w). It must be ich .. if it was something else wouldn't they be more affected?

They are in the tank by themselves, maybe 2 or 3 snails and a golden dwarf eel. I have been meaning to move the 3 into a new FOWLR I've been setting up but it's nowhere near ready. Once the new tank is cycled I can move the eel over, he's not affected by spots at all. I'm assuming maybe eels have more tolerance/immunity against ich?
