Ok! i broke down and bought 2 clams Saturday. the first clams we've gotten in a year or so, so i had to set up the QT. a QT can be as simple as you like or complex. i like simple. heres what i set up. its just 2- 20gal tanks in a storage room in the basement. i used a pump from my RO container, spare heater, and took about 25gal out of our main system and 5 chunks of live rock i had sitting in the sump. done in all of 25min. you can use a 10 gal tank if you like, with a simple foam filter(when not in use keep the foam in your sump) or a few chunks of LR and an air stone. you will be surprised how much water movement you get with just an air stone.
