I just setup my 20G long QT. To make the cycle run faster, I put some flake food, 1 live rock from DT and 1 filter pad from sump. Both of those have been in there for several days. Point to note, I am running cholorquine phosphate in the DT for 2 weeks now. I wanted to know if this will speed the cycle process in QT? If not, how about if I use Bio-Spira. How long does that take in a 20G system?
