I just setup a 10g QT, with pvc pipes from lowes. I bought a 10g starter kit with a mini-biowheel and an extra heater. I used water from the main tank and also a carbon bag from the main to to jump start the cycle time. However, I don't think my QT is fully cycled, yet. Just tested the water this morning, Ammonia is ok, but nitrites are high. I'm thinking about doing another water change soon. Fish in the QT seem to be doing ok, though. It's hard to keep the quality up without LS and LR.
