tunze 9010 work better in sump or hanging?

[Skeptic9962]

i finally got fed up with it constantly having microbubbles cause the way my sump was made was stupid it was made for skimmer/return pump in one chamber and that just doesnt work at all...so i thought it would finally break in and stop microbubbles but i just have a feeling that they where way too close to eachother for the bubbles to ever go away..the middle chamber of my sump was made so it would be a small fuge so i just tossed the skimmer in that section and hung it off the side of the sump it seems to be creating quite a bit of foam so far but was just wondering does that effect how good it works...got the micro bubbles to get way less then it was now you cant really see them...

basically im just wondering if this will decrease how efficient the skimmer is substantially...if so could i buy the foam extractor the kindof even out the loss?

thanks for any input =)
