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.

You need either a substrate for the nitrogen cycle to take effect or larg water changes. How much water to change, and how much media in you filter, will depend on bio load.

Because you have no established filter, you will likely be doing large water changes for a month. Monitor the cycle, change water as needed. Using some rock rubble out of your tank in the filter will greatly speed up this process, don't reuse it if your using chemicals.

NOTE! When you throw sponges away, you throw away lots of good bacteria. Don't do it till your done your hospital treatment.

I just have a canister filter with sponges inside running all the time, so it is ready and fully cycled whenever I need it. ATM, I am using mine to cook some rock.

Thank you all for your input!!!

I just picked up a nano filter that runs with a sponge that I can seed, and I can add a little carbon cartridge whenever needed.

I'm going to seed the Sponge tonight, and take it from there.

Thanks again EVERYONE!!!

Biological filtration isn't an absolute necessity.....large daily water changes can get the job done....

When I start my tank I grab water from the DT and an air spounge I have pre seeding. After all is over I throw the spounge out and start all over.
