I have had no real window to apply more than a couple of pounds at a time here. The fact that it has to be applied when there is NO wind makes it very frustrating. I might have to wait many months for such a day here. I know the product can be effective, but such wind restrictions negate a lot. A pond could go dry waiting for a totally calm day. Call me frustrated. Still losing 1/4 to 1/2 inch a day, it varies.
