hi---am looking for ways to stop a pond leak--have packed bottom with 2 ft. of good clay--in a couple of bad spots used the clay plus bentonite ---water now seems to be leaking thru dam-- need to tie repair into the clay already placed in bottom of pond. have questions on db100 and db200 products from those of you that have used them-- 1. are they safe for fish and human consumption of fish raised in ponds with them applied?
2. how long does the product stay "slick" and how long does it last after application?
3. can you avoid slickness by rototilling the db200 into the existing soil and tieing it into the existing clay bottom.
any info on these products and success with them would be most helpful.
i am most hesitant to apply products to my pond that i know nothing about the safety of. thanks
