Could micro bubbles be killing my cheato?

I've had it since I started my tank-January. My light is about 4" above the water and the cheato is near the surface because the sump is filled with live rock. I moved it to the side of the sump where the majority of the micro bubbles are and the problems seem to have started then. I did notice that air was being trapped in the cheato.

Can you put a baffle in the sump before the chaeto to calm the waters a bit?

It's too tight down there. I can barely fit my skimmer as it is. It's a 25gal tall and just fits in my stand. I'm going to a 120 down the road anyways. It'll have a seperate refuge. I'll have to keep playing around with what I've got for now. The best solution I can see for this system is to build a stand with some room for a bigger sump.
