My powerhead is a duetto-100. Not really
made for saltwater, but it filters some of
the gunk out. If I were you, invest in a
maxi-jet. I don't have a skimmer. But I
will be getting a "Prizm" skimmer. They are
the cheapest from what I have seen, and work
well. Place around here has it for $70. So
it should be around that price when you go
looking for it.
