JBM, welcome to Pond Boss. I understand PI but not LL. According to Mike Otto's book Just Add Water you should have a PI between 13 and 30.

Mike mentions several "field tests".

Moisten it and make a ball about the size of a golf ball. Drop it from about shoulder height. If it breaks apart, add more moisture and try again. If it passes the ball test, get a handful and start rolling it out like a cylinder. If it holds together when it gets pencil size, it ought to make a dam.


It's not about the fish. It's about the pond. Take care of the pond and the fish will be fine. PB subscriber since before it was in color.

Without a sense of urgency, Nothing ever gets done.

Boy, if I say "sic em", you'd better look for something to bite. Sam Shelley Rancher and Farmer Muleshoe Texas 1892-1985 RIP
