Looking for a powerhead

Hi all,

My powerhead bit the dust on my 28 gallon bow front salt water tank and I was wondering what I should replace it with. My tank has mostly pulsing Xenia and some mushrooms along with a couple of clown fish. I am running a HOB Reef Octopus protein skimmer on this tank. Since the tank is full of pulsing Xenia, just scraped them off the glass over the weekend so the bottom of the tank could get light again, I am not sure which powerhead(s) to get.

Thanks,

Glenn
