I have 2 little giants.... they are louder than my sequence Hammerheads. Depending on what kind of vertical lift you need I would look at a Dart and you could prob run your skimmer, media reactor, uv, ozone, circulation all off one pump. If you need more head you can get a Hammerhead for about 300 and you could run all those items and still lift up from a basement, run circulation, and bleed off into a sump with in sump circ.
I really like the Sequence stuff...
