Dan, my pond is about 1/2 acre and I put 12 packets in it. That's not as much as they recommend but I used the method subsribed to by many on this forum and recommended by the manufacturer. I mixed each packet with a couple of gallons of warm water and let it sit for 3 to 4 hours. They say the bacteria multiply fast this way and you end up putting much more into the pond than you actually bought. We'll see if it does anything.

Gotta get back to fishin!
