just setup my hob bakpak on my 20l again. its already pullin out a lotta stuff. my question is how will all my filter feeders do? i was always under the impression that the skimmer should pull out all the dt's and phyto feast wont it along with all the ohter gunk in tha tank. Another question, how do i eliminate all the micro bubbles this thing is putting out? i have the pre skimmer and bubble trap but have no clue were they go. any help would be really really appreciated
