My ice hole is almost frozen over now. I can see the barely see the bubbles thru the ice. After reading the exploding post I don't think I'll be shooting anything at the hole. Must have been something to see. If it dosen't open up, I might throw a large rock at the area.
My pump is a low cfm and is about 6 feet under the surface with about 1 foot to 18" of ice on the rest of the pool now.
