Hi, here is a good post by
@Humblefish for a bare essentials QT ...

Excerpt ....
How to setup a QT - The following are the bare essentials:
- Aquarium (10-30 gallons seems to work for most people. Bigger QT lets you house more fish and gives you more wiggle room when it comes to ammonia. Smaller QT is cheaper, easier to maintain and can be setup/broke down quickly.)
- Heater/thermometer
- Small powerhead or air pump/air stone, for circulation & gas exchange.
- Freshly mixed saltwater which has been fully dissolved and circulating for at least 24 hours. Alternatively, you can use DT water to fill your QT so long as you are confident that your display tank is disease-free. Do not siphon near the bottom of your DT, to prevent detritus from being transferred to the QT.
Optional/recommended equipment:
- Light (can just be a simple, one bulb fixture)
- Hang on the back (HOB) power filter, where carbon or even a “seeded” sponge (explained later) can be added
- Egg crate (used on lighting panels), which can easily be cut with snips to build a custom top to prevent fish from jumping
- PVC elbows (see pic below) used as “caves” in which the fish hide
- Seachem Ammonia Alert badge (see pic below)
Substrate and rock are best avoided in QT, as those can absorb many medications. However, one or two small pieces of live rock may be added for ammonia control, so long as they are coming from a disease free tank. The live rock will need to be removed once a disease is spotted and
before medications are used. Furthermore, the live rock must be considered “contaminated” once exposed to a fish disease, and left in a fallow (fish free) environment for 72 days to starve out any parasites. Or alternatively, sterilize it using a mild bleach solution; after a thorough rinsing & drying period, it can be reused as “dry rock.”
Ammonia control: Toxic ammonia, caused by fish urine/poop and uneaten food, needs to be closely monitored in QT. You can use a test kit (so long as
no medications are present) or a
Seachem Ammonia Alert badge (works even in the presence of medications).
Even the smallest traces of ammonia are toxic! Therefore, anything other than a “0” reading necessitates immediate action! You can perform a water change to reduce ammonia; or alternatively, use an ammonia reducer such as
Amquel or
Prime (so long as
no medications are present).
The use of “seeded” bio-media can help to break down ammonia. I personally use an
Aquaclear HOB power filter, utilizing the “foam insert” i.e. sponge it comes with. I “seed” the sponge (or multiples) in a high flow area of my DT’s sump (or you can put it behind your rocks) for at least one month prior to QT. This one month allows time for enough
beneficial bacteria to transfer onto the sponge, so that it may be used as biological filtration once placed back in the power filter and used in QT. An alternative (albeit expensive) way to instantly seed your sponge is to pour some
Bio-Spira,
Seachem Stability or
Dr Tim's Nitrifying Bacteria over it just prior to use. Below is a pic of the
Aquaclear HOB power filter and correlating “foam” sponge (you can buy additional sponges cheaply):
