https://photos.app.goo.gl/Pg3newj8k2BAk1XI3i am lowering pond hoping to eliminate some plants. i am not sure if i have chara or american pondweed. i have sprayed diquat, cutrine, and applied cutrine granular. i didn't have much luck. looks like i may have another foot to drop it to get below the depth the plant is growing. i have already lowered over 2 ft. should i spray the weed once it is out of the water or will it dry and die?
next, the pic above is something that showed up after a day or 2 of hurricane rain we had a month or 2 ago. i had just fertilized the grass around the pond a few days before the rain. can anyone id this green floating stuff? it isn't fa, it looks more like foam or a sponge type algae. it breaks apart easily. it is about 1/4" thick and usually floats around in patches about 6" in diameter.
