Thin oil slick on my pond
This morning I found a thin oil film on my pond. I have a 1 HP Tsurumi submersible pump, about 8 months old that I installed this spring replacing the old one after it quit.
My question is, can something other than the pump be causing the very thin oil film? Decaying leaves, dead frog in the intake or other? The pump is still running and the pond has not iced up at all yet.
Has anyone else seen this condition? Do I need another pump?
