pump for 180g? 6' head

[Milad]

What pump should I be considering for 180g with 6' head
I need it as slient as possiable so im up in the air between the
sedra 9000 or the ehiem 1262

not sure if the ehiem will be strong enough though.

Also the skimmer I might buy is going to have a sedra 9000 on it so I think it would be nice to have two sedra 9000s but i dunno.

thoughts? Im torn!
