Connecting two sumps

I am setting up a 120 gallon with a 30 gal wet dry. I have a second 20 gallon sump that I wanted to plumb together with the wet dry sump for extra water volume, more sump space for equipment, and to use as a possible future refugium. I am thinking about connecting the two sumps with two (2" or 1.5") bulkhead connections (4 bulkheads total needed). I am curious if anyone has done this and if 1.5" bulkheads will provide enough flow between the two sumps to keep up with a 1000 gph pump. It appears easy enough and straight forward but thought I would ask to see if someone has personal experience doing this.

why not get a bigger sump tank? I think the petco $1/gallon sale ends tomorrow, or this weekend.

I've never done what you're thinking, but it sounds like it should work alright. you could always set up baffles to direct flow to the bulkhead

Because I already own the custom made 30 gal acrylic wet dry and the 20 gal acrylic sump. It is also more economical to use what I already own versus going out and buying more stuff. What I am looking for is someone who has connected two sumps in the fashion and whether or not 1.5 bulkheads provide enough flow. If not, I will use some 2" bulkheads I already own that were intended for a different project.

i don't see why a 2 inch bulkhead wouldnt work. that size can move a lot of water,
i wouldn't think using the 1.5 as well would be needed.. i had considered doing this one mine with a 1.5 so i can have a separate sump for just co2

With what type of flow rate? My pump on puts out 980 gph and at the 4.5 head, maybe 825'ish. So it wont have a ton of flow between sumps. I can't imagine that two 1.5" not being enough, but again, I've never done this before.

Thanks for your input.

one 1.5 on each side would be enough
2 inch is just a margin for error, and upgrades maybe?
keep in mind though, there won't be any siphoning by gravity. you'll be installing a horizontal tube. water will move because it will have a new place to go. more or less
