Hi everyone...

My new 43 gal is cycled now and im waiting for t5 lights before i get all my plants.

When i brought my tank 2nd hand from ebay it came with 2x Eheim classic 2213 filters. The person said he was keeping oscars and that why he needed the filters.

I am currently using one of the filters and they have identical medium in both canisters. I have taken one apart to ask you whats in the black bag and what is the rock type ?

I know the white fluff is filter floss. But if the stuff in the black bag is carbon, will i need to take it out for when my plants arrive and what would i replace it with ?

Canister (to show the layers)


And the 3 filter medium:


Whats in the middle and whats on the right please.. Thanks
