I used the same method in the last tank I set up. I don't think it's 
so much preventing bacteria from multiplying. They will exist in the 
tank and filter to the extent that there is nitrogenous waste to feed 
them. It is rather a matter of not needing to plan for them - no need 
for bioballs or noodles or whatever in the filter. So it's not whether 
we should have biofiltration - we will, in any tank - but whether we 
need to provide a specific home for the bacteria. My experience is 
that we do not.
