I was going to polymer my pond, but the vegetation problem got in the way. I suppose I could put in seme grass carp to strip it clean first, but how do you easily get them back out? I could nuke the plants from orbit and wait for them to decay, but leaves on the bottom may still be a problem. It does seem like a new pond product to me.

Anyhow our ponds leak problem has slowed to a tolerable level, but I am definitely watching this story. A few folks near me could use this product.
