I run an Aquaclear HOB with a small rock in my QT tank at all times. Its just a rock with beneficial bacteria on it. It can absorb some copper, but I can work around that.

That's generally not recommended because it absorbs medications and will make it difficult to keep the proper levels of medication in the tank.
