How to Quarantine

[sphelps]

Been lots of discussion on quarantine tanks lately so I wanted to start a thread to allow people that quarantine their livestock to explain their quarantine procedures.

What size quarantine?
What equipment do you use?
What parameters do you monitor?
What treatments/chemicals/procedures do you use?
What do you quarantine? Fish, inverts, coral
How long do you quarantine?

Interested to see what people suggest when adding corals and inverts, how do you insure you don't introduce any parasites?
