Freakin micro bubbles

[Darbna]

Been running a 7 foot 265 Gallon LPS tank for several months now. I have 2 Gyres for flow on each side. Tank is 7 foot long. I been struggling with GHA for the last month or so and finally have it where it is removed. I have been noticing particles in the water column and was under the impression it was bits of algae. Well some was, since its all gone at this point, I still see specks floating around. Turns out I have micro bubbles. I have spent countless hours moving things around in the sump. I am at a loss. I have a sponge block separating the skimmer section from the return. There is also a refugium coming in that I also have placed a sponge filter block. I added power heads in the sump both by the return and in the skimmer section. I cant get it figured out and I am frustrated with it. Anyone experience this phenomena? I cant stand it.

Does your sump have bubble traps?

A picture would help if you can get one. Maybe add a bubble trap somewhere

the water goes through a sponge block and under one baffle. there is also a small water fall through some bio balls from the refugium on the back side
