I have read it can be done without but not suggested or recommended .
Between a good skimmer and live rock it's the main biological filtration .
Research a little .
Berlin method is one topic I am still very curious to find out a little more about .
My tank I have a canister filter that only has filter floss in it .
The majority of my filtration is done by my skimmer and live rocks .
The filter floss only polishes the water to keep it clear and beautiful . Lol
