Quarantine Tank

[kube]

hi guys, i bought everything to make my own custom sponge filter for my quarantine tank, my question after I make the sponge i know i want to leave it in my sump so that the bacteria can colonize on it, but do i need to run the air stone in it while its in the sump or can i just toss the sponge int there and not have a power head or air stone drawing water through it till i put it in the quarantine tank???

just put the sponge in the sump and when u r ready to use it, take it out and hook it up to the air pump
