my swc 150 bmk just broke in and was working great for like 4 days pulling some nice gunk. i added a new snowflake eel and the skimmer stopped pulling stuff. does a skimmer need to re adjust when new livestock is added? also when i empty my skimmer cup am i suppose to be cleaning out the gunk on the inside of the skimmer cup as well? or just inside where all the stuff gets collected
