I personally would remove a small portion of the seeded fluval sponge but only if the 30 gallon is completely cycled. Place the portion into the filter for the 112 gallon.
I am sort of new to this, but I have charcoal in both tanks should that be removed?

I personally don't use activated charcoal in any of my filters. I only use it to remove meds which I haven't done in years. Personally add more Bio Media instead of the activated charcoal.

I feel that charcoal can mask problems. A healthy aquarium will have a slight earthy smell if everything is stable.

I have 6 aquariums up and running never used charcoal in any of them during the cycle process.
