extra sponge works well for me in the ac70's

Id do one with 2 sponges or 1 sponge and 2-3 layers of blue filter padding, and the other just full of bio!
That way the cleaning is straight forward and IME its just more efficient that way! Not to mention that will polish your water very nicely without any additives to the chemical filtration (carbon,purigen etc). More natural this way, depending on your stock and setup.
