Adding a 3rd tank to a 20g sump is it feasible?

[GoReefin]

Hi all I have 2 13.5g systems with a 20g sump and wanted to add a 3rd tank to the system for mushrooms and zoanthid corals. It would go behind my current lps/softy tank.
It would be raised above the other tank for viewing.
I already plumbed a 3rd outlet for the main return pump in case I wanted to add something later. Was planning on building a box to set the third tank on to raise it up above the others.
My return pump is currently running at around 35% capacity

Do you guys think this would be feasible with a 20g sump?

As long as you have the flow to feed all 3 and the room for drain back if the power goes off or the pump dies, I see no issue. My old 90 gallon was supported by a 20 long sump for years and years.

Awesome! Looking forward to getting the third tank in.
