I was reading in another post that LR works as a bio filter, eliminating the need for any external filtration. Is this true? I've done a lot of reading and I've never heard this before today.
I've got a 55gallon reef with 75lbs LR and a 3-4" DSB and an Emporer 400 Bio-wheel filtration system. Can I lose the filters altogether and just keep the skimmer?
