2 Problems I need Help With. Please Help

Ive had a biocube skimmer on my 29 gallon and I've never got junk to empty out. I've adjusted many time and nothing.
Now, during a move, I got rid of my hang on refugium and got a 15 gallon tank and made that into a refugium and added a coral life skimmer. Same problem. No matter how I adjust it, all i get it clear liquid. I adjust it and bubbles rise above the cup, pour over and it comes out as clear water. My levels have always been 0 nitrates, 0 nitrites, 8.2 pH, 450 calcium, 12 dKh, 0 phosphates and 0 ammonia. Is there something I'm doing wrong, or do I just have nothing to skim?
Second problem, after the move and hooking up the new filtration, I've noticed brown algae growing in the refugium and in the overflow box. I've test and tested and still get the same results as I have always had them.
I do weekly water changes and never use tap water. What could be the cause of the brown algae?
The main tank is 29 gallons, the refugium is 15 gallons. I have a uv light running, a rio 2500 pump pushing the water to the tank, a overflow box returning the water to a filter sock that I clean out everyday, and a coral life super skimmer rated for a 65g.

Adjust it as high as you can and so no skimmate is made and it does not over flow. Leave it set like that for 3-5 days and if it does not make skimmate then feed heavy for 3 days to see if that will make some.
My levels have always been 0 nitrates, 0 nitrites, 8.2 pH, 450 calcium, 12 dKh, 0 phosphates and 0 ammonia. You have good water quality so I would try the wait and see if the new algae will go away on its own.

Agree with Geo on working in your skimmer.
As for the "brown algae", since you just moved the tank and added new things to it, I'm going to say that it's probably a Diatom bloom and it will die down on its own with time.

Thanks for the immediate help guys

Ill keep it posted with updates.
I've got my skimmer doing a "wet skimming"
Still nothing, but its creating some foam.
ANd as for the brown algae, hopefully it goes away soon.

If the skimmate is very clear then try to adjust it down, as little as you can, then wait three days. Like I was saying before if you feed a little heavy you can see more skimmed out for a day or two and that will help you know that it is set right.
