Best Flow for SPS 30" Tank

[Hentz]

Hey guys, so I've got 2 power heads I can use for my downgrade.
I plan on doing bare bottom to maximize flow in my little tank.

The tank will be 30"x15"x12"

I've got an MP10 and MP20 to use.

My question is, would it be better to use both on each side of the tank for chaotic and crazy flow?
Or would I be fine with just the MP20 alone in the tank?

I would use both. Counter flow can be a good thing and actually calm it down some.

I use 2 mp10s on a 20 long (30x12x12) and I like the flow a lot better then when I used just one.
