Adding frag tank to display

[Rvamalibu]

Howdy fellow reefers. So I'm fairly new to your forum and I've seen and read plenty of interesting things. So with that in mind id like to get some opinions and insight. So my display is a 150 gal and I'm wanting to add a 75 gal frag tank. However I don't really want to run an extra return pump or unneccesary plumbing. So I want to flow from my 150 to the 75 then down to 30 gal sump and return to 150. Anybody done this or have any suggestions recommendations or anything to point me in a good direction? Thanks in advance. Pics or vids are also appreciated.

You can do it separately, just T off the return to go to both tanks and plumb in the overflow of the frag tank to the common sump.

I'm running something similar right now when plumbing to share one pump for 2 tanks make sure to plumb in valves to each tank. This will allow you to make adjustments to the flow of each tank.
