TJ, if you read this, thanks again for your help. I do wonder if you are estimating a bit too aggressively on the amount of product that is needed? Several of us seemed to have at least half (or more than half) left when we applied it at the recommended rates. I had a .20 or .22 acre pond and was told to get 3 units. I used about 1.5, even putting it on heavy to try to get it at the recommended application dose. JoeDK has a smaller pond than mine at .15 acre and was told to buy 3 units as well?
Just wondered if we should have been advised to have about 1/3 less units recommended to start out with.
Not wanting to sound ungrateful as we appreciate what you do and the extra ended up providing me with 2 more applications at later dates which did some additional good too.
