There's a guy in Fremont selling that exact skimmer with an auto neck cleaner for a good price (half off retail). I can give you his info if you're interested in buying used. I passed on it because the external pump wouldn't work with my sump space, so I'm actually getting the space saver 220SSS elite version.
Yes please, thank you very much. And yes, this will fit into the sump the IM 150 comes with.
