Quarantine Tank Plumbing

[FishyFishy!]

I'm finally getting around to plumbing my 155 and all the sumps, frag tanks, water changing system etc etc. I'm wondering if I should plumb in my quarantine tank to the main system, or leave it stand alone.

I've read a few different opinions on this so far. The first being that you should plumb in with the main tank, because it will always share water perameters with the main setup, minimizing stress levels when transferring the fish in or out of the QT.

Next opinion is make it stand alone because it's tougher for acclimation to the new tank, but helps in the hospital/disease side of things. This is due to possible water bourne contamination, that might make is back into your display from an ill fish. A stand alone system will also make it easier to dose with medications so that is does not get into the main tank.

Whats everyone's position on this? I'm leaning towards stand alone, but as far as water perameters and ease of maintenance, it would be a lot easier to just plumb it in.
