Opinions On Hospital/quarantine Tank

Would there be any issues with cross-contamination between the QT and main tank by putting the filter from the QT back in the main tank after use? Would it need sterilised or something?

Just wondering as I've never needed/used a dedicated QT but do have spare tanks lying around if I did.

true, but i wouldn't put it back unless i'd done as fluttermouth says, well for treating disease anyway. (which i have never had to do, touch wood. scratches head)

unfortunately too few of us use them, as witnessed by the "help my fish are sick" post that litter this forum.

That's the main reason I bought it, this forum has made me paranoid .

my farther used to say "pre warned is pre armed".
I'd replace the word "paranoid" with "careful".
but it does mean, at least for you, this forum is doing its job.

I have a similar sized tank with a cycled filter. I keep mine cycled by keeping small guppy fry in mine since I pretty much always have them... and if needed, I can move them out and put sick fish in. (I've only got smaller fish so the size of tank works).
