Have have just given up on all of these budget busting products. The test ponds I have are all problematic with rocky aquifers. No liquod gunk is going to help that. In the old days, I mean centuries ago ponds were made by a technique called puddling. Where pondmakers compressed clay and straw, like adobe, into rock bottoms and had pretty good success. I know of guys that use horse manure, and clay. And you pretty much have to prep your ponds in some manner like this before you even try to use these products. I'm going back to old school for now.
