Does anyone know how many gallons per hour ratio I need for filtration
for the shark that I talked about in the General Saltwater Section? I do
not want to under filter it. I know that for the skimmer I am getting a
SeaClone 150 because that is rated 2x my tank size.

i think you would be safe using goldfish filtration rule tank size X 10= gph. example 29X10=290 gph

That is 720gph. Is 550gph enough?

id try two emporers 400s or do hobs work with sw?

HOB is not a good idea with saltwater.
