Hi Roger, Bulk Reef was sending you an email as well, kinda surprised they wouldn't exchange this for me when it was DOA. Anyhow it was doing nothing when i installed so I pulled it apart and found that the pump wont start unless bumped and wont restart then after either. The black piece on the front appears seated solid and correct (i found online some saying it would get bumped in shipping causing my issue) anyhow here is the video I made of the issue.
Thanks i'll look forward to your email
