Just setup my SM200 this past weekend. Looking at some of the photos and following the conversations here people are talking about the additional red line coming off the pump. I see clorox just put a black cap on it. I didn't receive a red line or cap with my skimmer unless it got discarded on accident. Do I need to cap that other inlet on my RD pump beside the air intake? What are the effects if I leave it open?
