Have a 20 g cycled tank with an aquaclear filter. Getting a smaller aquaclear filter for a 10 g not cycled. Can I take the sponge from the 20g and put it into the 10 g filter for a faster cycle? Will the new sponge effect the 20 tank? Can't run two filters in the ten because there isn't enough room on the tank and can't take the lid off because of the cat. Thank you.
