Getting a QT up and running in a pinch?

[rishu_pepper]

Thanks for all the advice so far, I think I have a much better grasp of what's necessary.

As for the water, that's my one confusion. Should I:

a) keep the current QT's water

b) change it out completely for newly mixed saltwater

c) half and half

These are my only real options at the time. I can possibly take 10-15g out of my RSM 130 if that's necessary, I'll just think of it as a water change for the RSM.

And how often do I do my WC in the QT? At what percentage?
