Question about starting a QT tanks

I have my DT running for 5 weeks now. The cycle is finished. I dosed 3PPM ammonia, and it was gone in 2 1/2 days. Ammonia is 0, Nitrite is 0, and Nitrate is between 20-50 (can't tell the exact number from the test kit)

I have 2 QT 20g-long. I have filter sponges been floating in the sump for few weeks, so I am going to using them to jump start the QT filters

My question:
Should I use 100% of the water from the DT, or 50% from DT and 50% fresh salt water?

Thanks,
 
Just use 100% fresh sw, it wont make any difference as bacteria is in the sand and rock, not much in the water.
