My cups fill up every few days at most. My asm skimmer has a huge cup so it goes even longer. BUT I skim very dry, not sure why but i have always preferred the thick skim over the soda colored water that alot of people skim. My asm pulls a tar like substance outta the water i have it set so dry. LOL
Just let it work it self out is my advice, you look like you are getting a decent skimmate so leave it for a few days and see if it needs more adjustment.
