i recently changed over to a penguin bio-wheel, from a whisper-type HOB filter... the water seems to have a ton on very very tiny air bubbles (i think... something very tiny circulating) which makes the water seem a bit cloudy... in fact when the filter is shut off, there are streaks, that look like smoke within the water... do the bio-wheels aerate the water very well or is this something else? and is there a way to make it not do this?
