Quarantine tanks...

[spencerC]

What would be required for them?
I have a spare 10 gal tank, I'm just wondering what else I would need equipment-wise to have it as a working quarantine tank.

Will I want to have substrate in there? Wouldn't that potentially house a bacteria/illness that the fish may have and pass it on to the next one who goes through?

Would a relatively simple/inexpensive filter work because of the 1-at-a-time inhabitance? Would i need a protein skimmer?

Would something like this work as well?
