Switched around a few things. I've moved the skimmer to the first section where the water drops in the refugium, this works out nicer I think and it frees up room in the return pump section. Also added one of those berlin media bags for catching any crap that falls into the refugium. Attached that to the water line that first enters the refugium. It's coming along so nice! I may add one more light though, I'm not sure if the single light I have is going to be sufficent enough.
I'll be slowly pulling the bio-balls out as my live rock gets more beneficial, because bio-balls are a pain in the butt IMO
so I don't want them in there. I simply moved them over just so I can have some good bacteria so I won't go through a second cycle. Gonna slowly remove them week by week, by the end of the month I should be good to go.
I agree not needing live rock in your sump, I have plenty of live rock in the top of my tank although I put some in the refugium just for the look of it and also so my macroalgae has something to wrap around.
Here's a pic of the switched around refugium:
