Cisco,
Just a quick question as watershed comes to mind. My pond was kept full from a field we farmed so fertilizer and everything else that went into producing a good crop had the extra washed into the pond for over 20 years.
Is there a chance that your pond, if filled by watershed, picked up some chemicals that is designed to prevent grass from growing? Did your soil test cover such items?
I have a lot of muck on the bottom of my almost 2 acre pond and from all the fertilizer that was used, I have a bloom that has lasted over 2-1/2 years without adding a thing, winter & summer, still going strong as of yesterday.
I am no expert, just thinking out loud from my limited experience on my pond.
