Ok I have had an epiphany!! I am going to be setting up a new 20g and I was wondering how to speed up the cycle because I want to move my loaches into it as soon as possible. I was originally going to use vacuumed water from my 30g tank and just dump it in. But now Im thinking what if I put in the bio scrubby thing (I have a tetra whisper ex 30 filter and they come with a blue and white thing for the good bacteria) in the 30g and wait for it to grow on there. Or could I run them side by side? Which option would be better or should I do something else?
