Changing Filters

Hello,
I recently setup a 55 Gallon SW Tank ( 3 months ago ) and i first started it with a AquaClear 50 and a Fuval 305. Now i finally got my Wet/Dry ready and i was wondering if there is a procedure about adding a new filter and removing the old ones.
I'm afraid the bacteria will be lost. Should i run both together?
Thanks, J
