My protein skimmer is long overdue for a citric acid clean (it's been over 2 years). However, it is filled with tube worms, feather dusters, and other critters. My tank is currently running very well and I don't want to change anything to disrupt the balance. What is everyones thoughts on how beneficial (or detrimental) these critters are in the skimmer?
