Just rinse your pad in old tank water (dechlorinated) real well at water changes and put back in. I don't use carbon often anyway. I'll use it every few months for a month. Keeping carbon in for too long can release chems into the tank (from what I hear). Like others stated, keep your old filter in with the new for about a month. What size was your old tank? If you have the same fish stock your BB will keep up so add new fish slowly so it has time to adjust.
It's the same exact tank... Same fish. 29g... I just needed a new filter.. Old filter was an old hand me down off of craigslist ... "Regent 30g" and was getting old and loud... Besides... Good excuse to get something new AND I wanted a great filter capable of handling the 40g i want in the future.
