What sicce DC return pump for 75 gallon tank

[guerino789]

Just wondering your thoughts on what model would be sufficient for a 75 gallon standard tank with a 800 gph overflow box.

I use the 6.0 sdc on my 60g. It runs at 55%. I think the 3.0 would be too small for me.

I use the sicce sdc 6.0 on my 40 gallon at 35%, I've had it 2.5 years now, never had a problem with it.

I used the syncra 4.0 on my 75 at full throttle, was more than enough
