Display refugium without sump?

[Tmr8188]

A thought crossed my mind earlier today and it seems like it would work.

 

So I have a lagoon 25 (12” in height).  If I was to block off the returns and feed the return pump directly into a tank next to the lagoon (in this case an Aquamaxx 18.1 approx. 14.6” tall).  The aquamaxx would be drilled with an internal overflow box and it would drain directly into the display area of the lagoon.

 

I can draw a picture if needed.  Is this possible without flooding my office?

I don't kow what tank you're using.  Is it an AIO?

 

This is how I set up my 40g breeder with a 20XH display refugium next to it.  There is a sump.

 

The return pump just feeds the tank.  There is a separate DC controllable pump in the skimmer section of my sump.  It's plumbed with vinyl hose up to the inlet on the bottom of the 20XH refugium.  The refugium has an overflow and a single bulkhead fitting to drain it downhill into the DT.

 

What happens when the power goes off?  Nothing unusual.  The refugium drains down until the water is below the overflow teeth.  Then it stops.  There's a standpipe on the inlet bulkhead, so as soon as that breaks siphon, the refugium is done draining.  The tank takes a few gallons of water from the refugium (at the most), and it drains down into the sump until the water is below the overflow teeth in the tank.  Sump fills up.

The lower tank is an aio.  It would be a very similar setup to what you have except the fuge tank would spill into the aio tank.
