Just to let you know, I used Bio Spira in all my QT Tanks and it took about 24-48 hours for ammonia to spike at .25 ppm then it went to 0 the next day and Nitrite started to spike. Nitrite rose to about 5.0 ppm over the next three days and then went to 0 and Nitrate rose to about 10 ppm then I did a water change and all is well. The whole cycle takes about 6 - 8 days and the spikes were not big enough or long enough to worry about.
Yes, Bio Spira is a bottle of good bacteria to help kick start the cycle for your QT, (not the DT). There is also API Quickstart and Dr Tim's One and Only if your LFS does not have Bio Spira.
I have used Bio Spira a few times now and it cycles the tank in 6-8 days with small Ammonia and Nitrite spikes that were not high enough or long enough to affect my fish. You could also take some filter media from your DT with good bacteria on it and place it in the filter of the QT. You would probably have to restart the counter on the QT at that time since you will be bringing Ich that hasn't been in the copper over, but the alternative is doing water changes every few days for the next 72 days since the cycle will never really complete that way.
