so im going to put my old matured filter into my new tank when its finished settling tomorrow, i have got exactly the same filter for my old tank

could i cut the filter sponge in half and put half in each tank? if i did how long would it be before i can stock the tanks?

they are tropical and both around 20 gallon tanks
put half of each sponge... so half new and half old in each tank
