Should I get a 6025 or 6045

[Duce]

I'm thinking of getting a nanostream to replace the existing PHs in my tank, mainly 1 of the 2 on the top in the picture. The pic is a bit old, most of the corals on the top are SPS right now. And I would like the Stream to point towards them.
With that said....sould I get a 6025 or 6045....as an Alt. I will replace the Seio in stead....the tank is 4' long.

I would go with 1 or 2 of the 6045. If you have some extra cash than a pair of 6055s would be perfect.

Yeah, I think 2 6045 is really the minimum for a 4ft tank.
