Could micro bubbles be killing my cheato?

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.
