My pump is only a 2" inch but i'm still thinking I could get 60 feet or so out of it if it was reduced down to a nozzle type sprayer. Thanks for the info...you've been really helpful!

Otto- leave some product for us..ha ha I'm trying to get my pond completely sealed off before this new demand for the product drives the product to unaffordable prices! I'm betting this produt will mysteriously keep going up in price as time goes on. I'm tempted to buy a few 100 gallons for future use and resale down the road..lol
