Not enough power heads?

[coral crazy]

I have a 55 with many new additions of corals and soft corals,my current is made by a aquaclear 400,a skilter 250,and 2 rio 200powerhaeds ,Do you think I need more current.

 

[fshhub]

that sounds pretty good. but for a more acurate answer, are there any dead spots?
and add up the gph of each unit, I would go with between 10x and 20x your tank size which would equal 550 gph total

I agree go with at least 10x your tank size. I have 3 maxi jet 1200's pumping 295gph, plus a magnum 350 sometimes pumps 350gph, and my main pump after reducing for length of water travel is about 550gph. So I'm at 1785gph in a 90g = 19.83x
