I appreciate the welcome guys. Couple things i left out or misled. My pond is over 40 yrs old. It on a mountain, and there are exposed rock surface in the basin that are 4-5 feet across. my feeling is that it leaks at the rocks. Also my water is extremely clear (can see bottom from 4 feet deep). so do you think i should supplement the db100 with a material that will coagulate with it? again thanks for the help!
