Reef Octopus BH90 has gone wonky

[AGWL]

I've been running my BH90 for almost 2 months and, except for a small electrical fire when it unexpectedly overflowed and killed a perfectly innocent surge protector, I've been thrilled with it. Fabulous, nasty skim.

However, the thing got filthy. Not just the collection cup, but the whole chamber was foul. So I took it down, cleaned it, and put it back up. No changes from before. Yesterday, the bubbles weren't rising enough, so I adjusted the intake and crimped the line to hopefully prime it.

Now the collection cup is filling with bubbles within minutes.

What am I doing wrong? And are y'all sick of me yet?

The water level in the skimmer may be too high; you don't want it foaming above the bottom of the collection cup.
