How do you get rid of a gurgling overflow?

Something looks really off with this set up and might just be me, but is there a chance<span style="color: Red"> that when (not if)</span> flow decreases in the refugium tank overflow it's just going to pour over the sides of the tank and flood your house. I would think that having an overflow in the display would help, or maybe raising the tank so that the tops match, or the refugium tank would be slightly higher, might stop a flood from happening.

Took a little bit to get my flows regulated but it works in kind of a tidal motion. It takes 6 hours for the tank water level to drop 2 inches while the sump level rises but at the 6 hour mark it starts emptying and tank level goes back up. The when the sump water level hits a certain point it starts filling back up. Please don't ask how I managed to do it that but it's really cool. Lol
