Welcome to Reef Frontiers!
My guess on your micro-bubble problem is that it's coming from your skimmer. That's a Coralife super Skimmer? It should have a bubble trap box that comes with it and you might check on-line for mods to reduce the bubbles as well. Also, those things overflow all the time. Just a matter of time till it pumps water out all over you floor if you're using it in the 'hang-on-the-back' position. Move it inside your sump if you can.
