Hello everyone.... Hope you are all enjoying the Summer so far. I'm at the point where I need to add a piece of liner to extend up out of the pond for my waterfall. It will of course be glued above water level by a couple of inches. My question is, which is safer for cleaning the liner along the glue strip line as it pertains to being safe for my KOI and other fish presently in the pond, denatured alcohol or rubbing alcohol? In scanning the net I see both mentioned but neither mentions the safety or harmfulness to the fish should any residue wash in at some point. I did read that denatured alcohol pretty much completely evaporates, but I figured I'd ask the experts here !! Thanks for any help or suggestions anyone might care to offer.
