Im not sure if any other company on the market has a "Watermeal guarantee" using a combination of products but I do know that SePro, manf of Sonar, does. If your pond gets a lot of runoff then I would look into using Clipper because it does not require a long contact time but you may possibly have to do a couple of applications. Otherwise contact Sepro and talk to them about your situation. They have been helpful to me in the past.
