One tunze 6055 in a 40G SPS tank?

[kimoyo]

Hey,

I'm putting together a 30"*24"*12.75" 40G sps tank. I was thinking about going with one tunze 6055 with a controller to pulse it or two 6025's or two Hydor KORALIA 3's. So do you guys think its better to have one pulsing powerhead or two non-pulsing powerheads? Thanks.
