Well, I received my HOB Octopus 100F yesterday and after playing with the setup for like 1 hour I finally got it working and is skimming yellow pee, seems to be working just fine... Now, should I keep my old HOB Biowheel Penguin Filter and have both my Octopus Skimmer and Filter working? Or should I take out the filter and just leave the Skimmer??? thank you....
