Our protein skimmers do a great job of removing organic waste from our aquariums, but they accumulate the foul smelling material into a collection cup that often stinks up the whole room. The buildup of this material prompts hobbyist to empty the cup every once in a while, but this also presents its challenges. The cup is emptied into a toilet, bathroom sink, and just about anything else that drains. However, like the leftovers from shaving, the skimmer gunk can leave a big mess wherever it is dumped. And while the leftovers don’t bother most hobbyists, their spouses might not appreciate it. So, when cleaning your skimmer, also be sure to clean up any leftovers that could cause you to get an earful.
