We're in a 2 bedroom rental and do not have a ton of space either. With a 25g FW and 25g nano reef tank there isn't space for a big QT tank. Here's what we do.
We use a 5gallon betta tank as a QT tank, bought it off a local B/S site for $15 with everything. Little filter, little heater with an LED light sits in the furnace room on a shelf with the 10 gallon RO bottles (we buy RO from local outfit, $2/per 10 gallon) and reef crystals. We also do not have a lot of room for a big QT tank. But it worked well enough for the 2 clowns then for some LR.
There's a big bag of Seachem Matrix in one of the HOBs on the nano so when QT goes into effect I pull some out and drop them in the filter of the QT tank. When QT is finished the Matrix is dried, bleached and boiled then goes back into the HOB. I keep more Matrix the needed in the main tank so I'm not worried about drastically effecting the bio filter by removing material.
The whole QT setup cost $15 (less water) and takes up no more space then a toast oven.
