My pond got the rotten egg smell after just a few minutes of running the blower. The pond had just filled up in June, and the pond had just been dug the previous Sept. It was an empty pond, nothing but dirt! I dont know what made the gas, but it sure happened fast. Since I didnt have anything in it yet, I just let it run and it has been running ever since. I have a single column of bubbles coming up from 17 feet down. Bobbi
