BuBBLES??

No way to tell from your diagram what we are looking at. I assume it is a side view but no pumps shown and it is not a conventional arrangement for a tank/sump. You could have bubbles because you did not use glue on a fitting.

I would get one of the perforated fish-keeper type of boxes and hang it so the water flows down through it into the tank. Then fill it with a handful of bio-balls to break up the bubbles. You could try filter floss but then it will start to trap detritus. You have a valve drawn on the line.
Photo shows concept. White tube is my drain from the tank into a sump. Refugium to the right. Water drops about 42" with no spray and very little sound.

A strawberry container would work, just something to contain a handful of bioballs to surround the water's exit. You could use a sponge with a hole punched in it for the pipe, except it will silt up at some point and may stop water flow. Bioballs will not retain detritus and cause water stoppage. I just did the exact fix last night where an intake in the sump was putting microbubbles in the display tank. We just laid a large 10" diameter sponge over the pump intake and it stopped the bubbles. However, as I said it will need cleaning frequently.
I mean to contain the water in the lower tank, not by putting anything in your overflow.

Lowering the return pump should help too. Bubbles rise so if you put in the lowest corner opposite the line into the sump it should help.

I am talking about the refuge(top tank)has a intake that is about 1/2" above the water and air is getting in the pipe. Then it goes down threw the pipes and out into the display tank. I am getting some huge bubbles not no micro ones either.
I need to stop that.

so what your saying is that the return line is too high in your fuge and its sucking in air????
if this is the case, buy an elbow and stick it on the intake....
