After adding cycled media (in this case an extra sponge filter that has been running in another tank for a month), how long should I wait before transferring my fish? I've got a 29 gallon that I've been running for the past two weeks while I waited for my plants to establish some new growth and for algae to form for my otos. I just transferred my filter an hour ago but don't want to jump the gun if it is inadvisable. Thanks!!
