I have the octopus 200 in-sump. It uses a single Sicce pump. I don't have a problem with it. The venturi on the air intake stays clean.
Every skimmer that I have used. Aqua-C EV series, Euroreef CS series, and now the Octopus will occasionally run over. That's why I keep the skimmer cup clean, and I use an in sump, so it doesn't make a mess. If I was using a recirc skimmer out of the sump, I would still have it in some kind of a container, or overflow pan.
