QT Filtration Necessary?

[gregzz4]

A QT is the best thing you can do for any reef tank.
You can dip corals, but you should QT critters.
Having a HOB filter is great to seed your QT. All you have to do is either float a sponge in your sump for awhile, or, run the HOB on your sump.
The point here is to seed a filter so your QT will support your dudes while you hold them in the QT.
Paraguard is a pretty basic remedy that is removed with carbon filtration, so don't run carbon while you're treating with it.
There's no harm using it with it's dosage, but you should remove it weekly with water changes. At the end of the week, do a 50-75% water change and change the filters in your HOB.
Don't keep/re-use the sponges/filters in your HOB - THROW THEM AWAY.
Especially if you use copper-based treatments.
Keep up your water changes ( if you have ammonia, nitrites), and make sure you have lots of aeration as most treatments cause your oxygen levels to drop.
