I woke up this morning to s silent and still tank. All of my equipment is running from this external GFI: Shop Shock Buster 6' 4-Outlet 12-Gauge Extension Cord with GFCI Circuit at Lowes.com I have two power strips running from this. In one power strip I have my return pump, heater, and skimmer. On I have all my lighting equipment running on the other strip/timer. I contacted the vendor and he was great. He is going to have a new pump on the way to me on Monday. Has anyone else had this type of failure on their skimmer running the Atman 2500 pump?
