That is what I am hoping is causing all the yuck. My water sure is clear, with the angle just right I can see the frog when they jump in to hide on the bottom, and I think the herons can too, they are getting less and less each day.
D.I.E.D
Its not at all stringy, breaks away when handled or disturbed. bubbles could be all the gases from the bottom of the pond, not uncommon to see 2-3 bubles streams at a time at different places of the pond
