Sorry i've been out of the loop for a while! I definately have considerable difference in seepage now. I still can't determine if what i'm losing is from seepage or evaporation but i'd say its at least slowed water loss down 60% if not more. I'm going to put another 6 gallons in because just as cheezy1963 said even if it doesnt slow or stop your leak (which in my opinion it does) it still is one hell of a water clarifier and is dirt cheap! Keep in mind also I dont have a leaking dam or what i would consider a hole in my pond. It just has a slow seepage over entire basin in my opinion so results may vary on different types of leaks obviously.
