Skimmy Dippin'...

[SaltNoob]

So, my skimmer on my RSM 130 was working fine for the past few weeks, but the past week or so the cup has been empty and no bubbly funk or anything of that nature. The pump is working fine and I've adjusted air intake but zero results.

Any thoughts/comments/ideas?
Thanks, salties.

Are your bubbles working, but there is no skim? Is you water height stable in the back part? I found a changing water height made a difference in how well the skimmer worked
