No advice, just sharing a bit...
What a frustrating experience breaking in skimmers can be. Mine took forever. Vinegar cleaning, height adjustments, speed adjustments (DC control) and still...wwwwwhhhhhhiiiiiiiissssssshhhhhh....all over my sump. New tank of course and luckily no livestock. After two weeks of letting it run like that I grew so flippin' frustrated...my dog would run and hide when she saw me opening the cabinet door in anticipation of the string of profanity that was sure to follow. Got so mad I turned it off for a week, hitting the power switch with as much attitude as I could muster. After a week or more, i turned it on again and sigh....wwwwwhhhhhhiiiiiiiissssssshhhhhh...all over again. This time it had won, I was a beaten man. "Heck with it, let run like this forever, I don't care".
Three days later, opened the cabinet, there's no "wwwwwhhhhhhiiiiiiiissssssshhhhhh" sound and a tea colored skimmate sitting pretty as you please in the cup.
Dog no longer runs, but still keeps an eye on me opening the cabinet door...just in case I presume.
