Is there any downside to letting my skimmer run WITHOUT the collection cup? I added a bit of nw rock this weekend along with a lot of gluing of frags. My skimmer is going crazy. Instead of dumping the cup filled with basically water, can I just let it run without the cup for a few days? Or is it better to just shut it off?
