Powerheads for 90 gallon fish tank ????

[Rolo1990]

I am setting up a new 90 gallon Marineland fishtanks, 48 x 18 x 24

I was thinking about how many powerheads I need. I currently have on my old tank a nero 3 should I go with two nero 5’s or 1 nero 5 or just stay with the Nero 3 is that enough?

I would do 2 nero 5’s at least
