Return pump upgrade

[pastelball]

Looking to upgrade my return pump. I have a mag 3 now that is working fine. I am planning a tank upgrade. Looking at the waveline pumps now. The height is about 4 feet. I have a single 1 1/2" over flow. And 3/4" return. Any suggestions on a decent return pump.

I have a 25 gallon cube. Going to go with a 60 cube later

The DCT4000 is a good pump. I'm using one for my return and it runs very quiet. I'm also using a DC3000 for my manifold. Really like the controllability of the DC pumps. Allot less heat than the Mags.
