Trying to understand cycling sponge filters and have been finding different answers all over the internet. My first question is, can I seed a sponge filter that I plan to use for a quarantine tank by putting it in my main display tank for 5 weeks without an air pump running to it? It would be a double sponge filter that sticks to the side with suction cups, only meant for a 10gallon. My second question is, some people say to just clean bio media in tank water and let the sponge filter run in that water? Could I take lets say a bucket of tank water and clean my HOB filter biomax and sponges in that water and let the new sponge filter run in that to cycle?
