I recently set up a SSS5000 and like it very much...Tank has only been set up completely for a few days now so I can't speak on performance but the quality of construction is top notch. Very easy to remove the cup, too.
This is what i got for my 210, I added the additional injector and quick release (helps with height restrictions for easy removal of the collection cup).
They are a sponsor so the discount applies - I am going to run it in sump with a mag 24 pump. Sump water level in your skimmer section cant be too high, i beleive the recommended is 10" so you may need to raise it up a bit if your baffles are higher in that section. Im excited to see its performance
