Which size Sicce return pump?

I am building a 40 breeder SPS tank and I am looking for a return pump. I have a Reef Savvy Ghost overflow, and I was looking at the Sicce 2.0. Any ideas thanks in advance.

I use a Sicce 2 on a 120 gal with rear overflow but no sump.

Either 1.5 or 2.0, depends on head height

3 ft head height Thanks I will go with the 2.0.

I use a 3 on mine. It is left over from my 75 and works well
