But I'm not sure how to plumb it. This is supposed to be a 3 tank sump i found. Any idea how to plump it?

This is actually three separate display tanks, no sump here!

The larger one has an internal overflow box, and looks promising!

The smaller two have a simple single drain, single return… great for a frag tank or remote refugium!

— typically, sumps have baffles, and no holes drilled below a possible water line! (Except when using external pumps)

I thought for sure the 60 was a display tank. I wasn't too sure about the 20 gallon tanks. Strange it was listed as a sump. Was a $100 for everything so i bought it and figured i'd just figure it out later. Figured i can always use the one for my quarantine tank once i get the 200 up and running
