Here are some pics of the scum...red and green today! Comments please...
Here's the pond we're working on. 6 acres, 16' deepest, averate 6'. 15 years old. Gazebo is 40' in diameter with mahogany deck and shake shingle roof (has electric and water).
Scum in a leg towards the road...very shallow.
More of the leg.
