I've also got a hold of some one flush in larger quantities. I'm trying it comparing to some other commercial grade bacteria�s. So far the one flush is doing quite well. Pond cleared up from a cloudy condition very quickly and the algae growth has slowed down dramatically. Now, I know this could be because the heavy growing season is over, but in the past, I had to fight algae all season long at my site. Now, it's just gone! I will continue to treat with the one flush and report. The distributor told me that some customers do use this for larger scale bio-remediation, so there may be some history here. Also the quantities they recommend are much less than other pond bacteria�s. I have an approximately 1 million gallon pond and they recommend 0.5 pounds weekly. Very cost effective if this works out.
