I have read all the resposes and still have the same question. I understand I need to do a test dig and I will do it before prodeeding with one method or another. Has anyone used ESS-13? I am trying to do research on differnet methods if I need to seal the pond. Can anyone other than the company that produces ESS-13 tell if it works? Or should I look into some type of liner if I need to seal the pond?
